XC6806 Series ETR25009-004 Lithium-ion Linear Charger IC with Shutdown and Current Path Function ■GENERAL DESCRIPTION Equipped with a system power supply function, the XC6806 is a linear charger IC for single-cell lithium ion batteries and lithium polymer batteries. The current path function gives system power supply priority over charging the lithium ion battery. The charge current can be adjusted with an external resistance, and an internal limit circuit with an input current of 450mA automatically reduces the charging current based on the load current that flows to the system. The lithium ion battery temperature is monitored in conformance with JEITA, and by controlling the charge voltage and charge current as appropriate for the temperature, the battery can be charged safely. Internal protective functions include the charge timer, UVLO, thermal control, and reverse current prevention. Shutdown function completely shuts off power supply from the battery to the system to prevent battery leakage current while the device is not in use, and this enables longer use of low supply current devices that operate using a small battery. Charge status, connection status with USB can be confirmed with CSO terminal and PGB terminal. The IC is mounted in the small, high heat dissipation USP-10B or LGA-10B01 package, and a charging circuit can be designed with minimal external components. ■APPLICATIONS ■FEATURES ●Wearable devices ●Bluetooth headsets ●Wireless earphone/Bluetooth earphone ●Hearing Aid ●Health care devices ●IoT sensors Operating Voltage Range Charge Voltage Charge Current : 4.5 ~ 5.5V : 3.50V ~ 4.45V ±30mV : 10mA ~ 385mA Can be set by external resistance : 450mA, fixed internally Input Current Limit Battery Sink Current Functions 0.1μA (Attached Battery only) : Current Path : JEITA Conforming Thermistor Detect : Shutdown Protection Function : : : : : : : Operating Ambient Temperature Package Environmentally Friendly Charge Timer UVLO Thermal Control Reverse Current Prevention -40°C ~ 85°C USP-10B, LGA-10B01 EU RoHS Compliant, Pb Free ■TYPICAL APPLICATON CIRCUIT VIN Li-ion Battery CIN OUT 1μF CBAT COUT 10μF BAT CSO VREG PGB THIN SD ISET VSS 1μF Protection IC 10kΩ CREG 0.1μF Thermistor (NTC) RSET 1/20 XC6806 series is Discontinued.

If the system load current is 450mA or higher, the input current limit (IINL) activates and charge of the lithium ion battery does not start. When the load current is less than 450mA, charge starts. ●Tricle Charge：0.5 hour If the BAT pin voltage has not reached 2.9V(VTRK), the lithium ion battery is charged at a current that is 1/10 the main charge current. If the BAT pin voltage rises to 2.9V(VTRK) within 0.5 hours (tTRK), the IC transitions to main charge after 4ms. During trickle charge, the CSO pin output is ON. If the BAT pin voltage does not reach 2.9V(VTRK) after 0.5 hours (tTRK), the IC transitions to the abnomal mode and charge stops. ●Main Charge：5 hours When the condition for charge from trickle charge to main charge is satisfied, the lithium ion battery is charged at the charge current set with the external resistance (RSET) connected to the ISET pin.During main charging, the CSO pin output is ON. If the BAT pin voltage rises to the charge voltage (VCV or VCVH) within 5 hours (tCHG) and the charge current drops to the charge completion current, which is 1/10 the charge current set with the external resistor (RSET), the IC transitions to the charge completion after 4ms and charge stops. If the charge current is still higher than the charge completion current after 5 hours (tCHG), the IC transitions to the abnomal mode and charge stops. The main charge current can be set to a value from 10mA(IBATL) to 385mA(IBATM) using an external resistor (RSET). The charge current value (IBAT) set with RSET is approximated by the following equation. RSET (kΩ) = 421 x IBAT-1.08 (mA) ●Charge Completion When the condition for transition from main charge to charge completion is satisfied, charge of the lithium ion battery stops and the CSO pin output turns OFF. Reset takes place when the power is turned off-on or the lithium ion battery is reinserted. ●Recharge Function When the BAT pin voltage drops from the charge voltage (VCV or VCVH) to 0.1V (VRC) after charge complettion, charge automatically resumes after 8ms elapses. ●Abnormal Mode If trickle charge continues for 0.5 hours (tTRK), or main charge continues for 5 hours (tCHG), an abnormal is detected and charge stops. When an abnoemal mode, the CSO pin output oscillates at 1 kHz.Reset takes place when the power is turned off-on or the lithium ion battery is reinserted. 7/20 XC6806 Series XC6806 series is Discontinued. ■OPERATIONAL EXPLANATION (Continued) 500mA 450mA IOUT 65mA 0mA 450mA 385mA IVIN 0mA 385mA IBAT 0mA -65mA 4.6V Battery Voltage 3.95V VOUT 0V 4.6V 3.95V Battery Voltage VOUT 0V Power is supplied to the system from the OUT pin at the same time as the lithium ion battery is charged. A current limit function is incorporated, and while the input current limit is not exceeded, priority is given to supply of power to the system than charge current to the battery. If the load current to the system exceeds the 450mA input current limit (IINL), current is also supplied from the lithium ion battery by the battery discharge control function.When the OUT pin voltage drops below the BAT pin voltage by 0.1V or more (VBD) during supply from the battery, the Pch driver between the OUT pin and BAT pin turns ON. When there is little load current from the OUT pin, the OUT pin outputs 4.6V (VOUT). When the load current increases and together with the charge current exceeds the 450mA input limit current (IINL), the charge current is decreased and the current from the power input pin VIN is held at 450mA. At this time the OUT pin becomes the battery voltage if the battery voltage during charging is 3.95V or higher. If the battery voltage is lower than 3.95V, 3.95V(VOCCR) is output. If the load current increases further and reaches 450mA or higher, current is also supplied from the lithium ion battery and the OUT pin voltage becomes the battery voltage. Note that when the VIN pin voltage is low and the input current is large, the current is limited to a value smaller than the 450mA input current limit (IINL), as determined by the ON resistance of the output driver. In this case, a drop in the OUT pin voltage and charge current will occur, but charging will continue. 8/20 XC6806 series is Discontinued. XC6806 Series ■OPERATIONAL EXPLANATION (Continued) < Lithium Ion Battery Temperature Monitor Function > The XC6806 monitors the temperature of the lithium ion battery by means of an NTC thermistor connected to the THIN pin, and controls the charge current and charge voltage based on the temperature to safely charge the battery. NTC temperature detection conforms to the characteristics of the NCP15XH103F03RC of Murata Manufacturing Co., Ltd.

When Thermistor Temperature≦0°C(VT0), charge and the timer count pause. While charge is paused, the CSO pin output is OFF. Normal Operation When 10°C＜Thermistor Temperature＜45°C(VT10, VT45), the battery is charged at the charge current IBAT and the charge voltage VCV. Hot Operation When 45°C≦Thermistor Temperature＜60°C(VT45, VT60), the charge voltage switches to VCVH and charging continues. When Thermistor Temperature≧60°C(VT60), charge and the timer count pause. While charge is paused, the CSO pin output is OFF. ●Type B (3 Temperature Monitor 0℃, 10℃, 45℃) Unlike Type A, Type B does not have 60°C(VT60) monitoring, and at 45°C≦Thermistor Temperature(VT45), charge and the timer count pause. While charge is poused, the CSO pin output is OFF. ●Type C (2 Temperature Monitor 0℃, 60℃) Unlike Type A, Type C does not have 10°C(VT10) and 45°C(VT45) monitoring, and when Thermistor Temperature≦0°C(VT0) or Thermistor Temperature≧60°C(VT60), charge and the timer count pause. While charge is paused, the CSO pin output is OFF. ●VREG Pin The VREG pin is a reference voltage output pin for internal and external NTC thermistor temperature detection. Connect a 0.1μF capacitor CREG and 10 kΩ resistor. (■Refer to the typical application circuit.) 9/20 XC6806 Series XC6806 series is Discontinued. ■OPERATIONAL EXPLANATION (Continued) When the VIN pin falls below 4.1V (VUVLOH) or below the lithium ion battery voltage and the UVLO function activates, the OUT pin and BAT pin conduct via the Pch driver. When High level voltage (VSDH) is input into the SD pin in this state, the rising edge turns OFF the Pch driver between the OUT pin and BAT pin, breaking conduction between the battery and the system.When the power input pin rises above 4.2V (VUVLO) and above the lithium ion battery voltage, and the UVLO function is released, the shutdown function is released. The SD pin includes an internal pull-down resistance (RSD). ●UVLO Function When the VIN pin falls below 4.1V (VUVLOH),or below the lithium ion battery voltage, the OUT pin and BAT pin conduct via the Pch driver, conduction between the VIN pin and OUT pin is broken by the Pch driver, and the IC stops operating. When the VIN pin rises above 4.2V (VUVLO), and above the lithium ion battery voltage, the IC starts. ●Thermal Control Function A thermal control function is incorporated to prevent destruction and thermal runaway due to heat generation in the IC. When the chip temperature reaches 95°C (TCS), the input current limit is reduced. An abnormal mode does not occur when the thermal control function activates, and the CSO output does not change. ●Back Current Protection Function To prevent reverse current from the Lithum ion battery to the charger, this function monitors the potential difference between the BAT pin voltage VBAT and the VIN pin voltage. When VIN drops to VBAT + 0.07V, the Pch driver between the VIN pin and OUT pin turns OFF, and in addition the backgate connection of the Pch driver is switched from the V IN pin to the BAT pin. When VIN rises above VBAT+0.1V, this function is released, the Pch driver turns ON, and the backgate connects to the V IN pin. ●Timer Reset In theconditions below, all timers are reset. ・ When UVLO is released (VUVLO)at power ON, and at battery connect detection (VTD) when the lithium ion battery is inserted. ・ When charge resumes after a load current higher than the 450mA input current limit (IINL) flows to the system and causes charge to stop, and current is then supplied to the system from the battery and the load lightens to less than the 450mA input current limit (IINL). 10/20 XC6806 series is Discontinued. XC6806 Series ■OPERATIONAL EXPLANATION (Continued) ●Low Voltage Operation for the OUT Pin The IC stops in operation when the OUT pin falls to 2V or less as the OUT pin is shorted to the ground. In this case, the IC restarts when UVLO is active and release. The input current for the VIN pin is saved 25mA when the IC starts after the OUT pin is 0V by the shutdown function or the external Lithium ion Battery Protection Function. It is supplies up to the 450mA input current limit (IINL) when the OUT pin rises over 2V. CAUTION 1 Additionally, some Li-ion/polymer battery protection circuits conflict with the OUT pin low voltage limiting function. Please check the following specifications of the battery protection circuit. ・ Please use the type that completely cuts off after overcurrent detection until the voltage is re-suppulied from the charger. ・ Please refer to the following when using the type that automatically recovers from over current detection when the load current detection when the load current decreases after detection of over current. Some battery protection circuits are held in a state where the battery and the protection circuit output are connected with a certain resistance “R” value when over current is deteced. In this case, even if the load current decreases, the current and the “R” are balanced, the BAT pin may be held at 0.5V to 2.0V, and charging is not restarted by the OUT pin low voltage limiting function when a voltage is provided to the V IN pin of this IC. After detection of over discharge, there is a type of protection IC that automatically recovers from over discharge protection when the battery voltage re-rises without applying voltage for recharging, then switches to overcurrent protection function. In case of this type, please check above. CAUTION 2 When the XC6806 start up, the BAT pin must 0.5V or less or 2.0V or more. If it is between 0.5V and 2.0V, the OUT pin low voltage limiting function operates and a battery will not be charged. When restart from 0.5V or less, the OUT pin low voltage limiting function temporarily stops until the OUT pin exceed 2.0V. The supply current from VIN is limited to 25mA until it reaches 2.0V at the time of restart to avoid the case where the load circuit is short and other problems. With this 25mA limit and the OUT pin low voltage limiting function, ・ COUT should be nominally 47μF or less. If larger COUT is used, the OUT pin low voltage limiting function may operate at restart. ・ When the load current is large, there is a case where is does not start up due to the 25mA limit. Therefore, please delay start of the load circuit to wait for the rise of the OUT pin voltage of XC6806. For example, we recommend measures such as a CR delay to the CE(EN) terminal of LDO and/or DCDC of a load. 11/20 XC6806 series is Discontinued.

Even temporary or transient voltage drops and rises may cause deterioration or destruction if the absolute maximum ratings are exceeded. 2. If the wiring has a high impedance, the output current may cause unstable operation. In particular, strengthen the wiring of the VIN, BAT, and OUT pins. 3. Place the input capacitor (CIN), output capacitors (COUT, CBAT, CREG), and charge current setting resistor (RSET) as close as possible to the IC to keep the wiring short. 4. An overcurrent protection function is not provided for the current from the BAT pin to the OUT pin. Exercise sufficient caution to ensure that the current does not exceed 500mA. 5. This IC is not integrated the over current protection function from the BAT pin to the OUT pin and the over discharge protection function so should build separately the protection functions for the Lithium Ion Battery. 6.This IC uses an external thermistor for high-accuracy detection and control of temperature. Test the position of the external thermistor sufficiently to verify that temperature can be accurately detected. 7. Risk of destruction if the battery polarity is reversed. Never use with the polarity reversed, as safety cannot be guaranteed in the event that the IC explodes. 8. Short-circuiting to an adjacent pin may cause malfunctioning and damage. Exercise caution during mounting and use. 9. A large ripple voltage on the VIN pin may cause the IC to malfunction. Test sufficiently before use. 10. The set charge current must always be within therange 10mA to 385mA. 11. Do not connect anything other than a resistance to the ISET pin. 12. Do not use the reference voltage output from the VREG pin for any purpose other than NTC thermistor temperature detection. 13. The charge is stopped lower than the setting voltage by the back current protection if the charge voltage is set high and the input voltage is low. 14.
