XC6805 series is Discontinued. XC6805 Series ETR25007-005 One Cell Li-ion/Li-polymer Linear Charger IC with Battery Temperature Detection ■GENERAL DESCRIPTION The XC6805 is a Constant-Voltage (CV) and Constant-Current (CC) type charging IC for linear charging of single-cell Li-ion batteries and Li-polymer batteries. The basic charging cycle consists of trickle charge mode followed by main charge mode. This IC supports temperature control based on JEITA, making it possible to safely charge Li-ion batteries and Li-polymer batteries by controlling the CV charge voltage and CC charge current according to the temperature. By connecting a resistor to the charge status output pin, it is possible to check the charge condition via the charge status output (CSO) pin voltage. The IC is housed in the small USP-6EL, USP-6B07 package with high heat dissipation, and a charge circuit can be configured using a minimum of external components. ■APPLICATIONS      ■FEATURES Small Battery JEITA conforming Thermistor Detect Function Built-in Wearable Device Operating Voltage Range : 4.5V ~ 6.0V Fitness Tracker Supply Current : 100μA (VIN=5V, VBAT=3.5V) Hearing Aid CC Charge Current : 5mA ~ 40mA (Can be set by external resistance) Smart Meter CV Charge Voltage : 4.2V, 4.05V (at high temperature) Internally fixed Protection Circuit : Thermistor detection function (Except for the XC6805xN) Safety timer function UVLO (Under Voltage Lock Out) Thermal shutdown (Latch Stop) Dropout voltage monitor function Charging over-voltage monitor function Charging over-current monitor function Recharge function Operating Ambient Temperature : - 40°C ~ 85°C Package : USP-6EL, USP-6B07 Environmentally Friendly : EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT CSO VIN ISET RISET Li-ion Battery BAT 4.5 ～ 6 V CIN 1µF XC6805xN NF CL 1µF Protection IC VSS 1/25 XC6805 series is Discontinued.

Series ■OPERATIONAL EXPLANATION XC6805xxE IBAT ≤ C x 0.1mA under 5 hrs Main Charge： 5 hrs VBAT ＜ 2.9V under 5 hrs VBAT ≥ 2.9V under 0.5 hrs Abnormal Mode Completed Charge Trickle Charge： 0.5 hrs Charge Start Re-attached Battery or Re-input Power Supply Re-attached Battery or Re-input Power Supply or VBAT ≤ 3.9V (*1) XC6805xxD IBAT ≤ C x 0.1mA under 5 hrs Main Charge： 5 hrs Charge Start Abnormal Mode Completed Charge Re-attached Battery or Re-input Power Supply Re-attached Battery or Re-input Power Supply or VBAT ≤ 3.9V ●Charging start When a thermistor is connected to the THIN pin after a voltage is applied to the power input pin (①), or when a voltage is applied to the power input pin after a thermistor is connected to the THIN pin (②), the power on reset function activates and initializes the internal counter. After 200ms elapses in the case of ①, or 150ms in the case of ②, charging starts. ●Trickle charging: Less than 0.5 hour (XC6805xxE only) Trickle charging determines if main charging of the Li-ion battery is possible. The Li-ion battery is charged at a trickle charge current that is one-tenth the charge current set with the external resistor R ISET. If the BAT pin voltage VBAT is above 2.9V in the charging start state, trickle charging takes place for 1ms and then main charging begins. If VBAT is less than 2.9V, trickle charging takes place, and main charging begins 50ms after 2.9V is detected. If the BAT pin voltage is less than 2.9V after 0.5 hours, the IC changes to the error state and stops charging the Li ion battery. In addition, the error in the trickle charge current increases if VBAT drops below about 1V. ●Main charging: Less than 5 hours When the condition for transition from trickle charging is satisfied, it is determined that rapid charging of the Li-ion battery is possible and the IC changes to the main charging state. In main charging, the IC charges an Li-ion battery at a CC charge current that is set with the external resistor RISET. If the BAT pin voltage VBAT rises to the CV charge voltage VBAC within 5 hours, the charge current drops to the charge completed current, and after 50ms elapses, the state changes to charge completed and charging stops.If the charge current is higher than the charge completed current after 5 hours, an error state occurs and charging stops. ●Charging completed When the charge current reaches the charge completion current, which is one-tenth the charge current set with the external resistor RISET, and after 50ms elapses, the IC changes to charging completed and stops charging the Li-ion battery. At this time, the charge status output pin changes from ON to OFF. When the BAT pin voltage (VBAT) falls from the charge completion state to the recharge voltage VRCHG or less, charging automatically restarts. When a voltage is reapplied to the power input pin or a Li-ion battery is reconnected to the BAT pin in the charging completed state, the IC starts up and charging begins. 9/25 XC6805 Series XC6805 series is Discontinued. ■OPERATIONAL EXPLANATION (Continued) ●Error state If it is determined that charging is abnormal in any state, the IC treats this as an error state and stops charging. When the power is turned off and then on, or the battery is reinserted, the IC starts up again and chaging starts. An error state occurs if 0.5 hours elapses during trickle charging, if 5 hours elapses during main charging, or if thermal shutdown, charging overvoltage, or charging overcurrent is detected. ●Charging status output pin (CSO) The charge status output pin turns ON by Nch open drain output during trickle charging and main charging, and turns OFF after charging is completed. If an abnormal condition is detected, the charge status output pin repeats ON-OFF at 1kHz on the XC6805A, and turns off on the XC6805B. ●Charge current The set charge current of the IC, ICHG, can be set within the range 5mA to 40mA by an external resistance (RISET). The RISET and ICHG are approximated by the following equation. RISET (kΩ)=351 x ICHG -1.11 (mA) ●IC temperature monitoring function In order to prevent destruction due to IC heat generation as well as abnormal charging due to thermal runaway, a thermal shutdown circuit is incorporated into the IC. If the chip temperature rises to 140°C or higher and after 50ms elapses, the output driver is turned off and charging is stopped. At this time, the charge status output pin repeats ON-OFF at 1kHz on the XC6805A, and turns off on the XC6805B. When voltage is reapplied to the power input pin or the Li-ion battery is reconnected to the BAT pin, the IC starts and charging begins. ●Dropout voltage monitoring function To prevent reverse current from the Li-ion battery to the battery charger, this function monitors the dropout voltage between the BAT pin voltage (VBAT) and power input pin voltage (VIN). When the VIN falls to VBAT +40mV, the function turns off the output driver and switches the backgating connection of the driver from the power pin to the BAT pin. When VIN rises higher than VBAT+0.1V, this function is released, the output driver turns ON, and the driver backgate connects to the power pin and charging resumes. In addition, this function continues the tCHG count even when charging is stopped, and the charge status output pin maintains the ON state. After charging is completed, the charge status output pin remains off even if the function activates due to the input power being removed or otherwise. ●UVLO function A UVLO function is incorporated. If the power input pin falls to 3.8V or lower during charging, this function turns off the output driver and stops charging. In addition, charge status output pin changes to OFF. When the power input pin rises to 4V or higher, the IC starts up and charging begins. This function also detects voltage application to the power input pin. ●Charge over-voltage monitoring function This function stops charging to prevent charging the over-voltage battery if the BAT pin voltage is 4.45V or higher and after 50ms elapses. At this time, the charge status output pin repeats ON-OFF at 1kHz on the XC6805A and turns off on the XC6805B. When voltage is reapplied to the power input pin or the Li ion battery is reconnected to the BAT pin, the IC starts and charging begins. (*1) ●Charge over-current monitoring function To prevent charging of a battery by excessive current, this function stops charging if the charge current rises to 110mA or higher and after 50ms elapses. At this time, the charge status output pin repeats ON-OFF at 1kHz on the XC6805A and turns off on the XC6805B. When voltage is reapplied to the power input pin or the Li ion battery is reconnected to the BAT pin, the IC starts up and charging begins. (*1) ●Recharge function With the completion of charging, when the NTC thermistor temperature is 0°C or higher and less than 45°C, and the BAT pin voltage (VBAT) falls to 3.9V or less, charging resumes. (charging is resumed 150ms after the charge start state is entered). On the XC6805xx4, if the NTC thermistor temperature is 0°C or higher, less than 45°C and BAT pin voltage(VBAT) drops less than 3.9V, charging automatically resumes. If the NTC thermistor temperature is 45°C or higher and less than 60°C, charging automatically resumes when the voltage falls to 3.75V or less. (*1) Insertion and removal of the battery is detected by thermistor connection (THIN pin voltage). For this reason, restarting of the IC is not possible by battery reinsertion on the XC6805xN, as the THIN voltage is fixed to the internal IC. When voltage is reapplied to the power input pin, the IC starts up and charging begins. 10/25 XC6805 XC6805 series is Discontinued. Series ■OPERATIONAL EXPLANATION (Continued) ●Li-ion battery temperature monitoring function (*1) The IC monitors the Li-ion battery temperature during charging by means of an NTC thermistor (“thermistor” below) connected to the THIN pin. The charge voltage VBAC and the charge current IBAT are controlled based on the Li-ion battery temperature as shown below to enable safe charging. The charge state changes after the Li ion battery temperature reaches each of the change points and after 50ms elapses.

(*3) ●XC6805x3 (3 temperatures monitoring) Comparing to the XC6805x4, the XC6805x3 does not monitor at 60°C and charging stops at 45°C ≤ Thermistor Temperature. (*2) ●XC6805x2 (2 temperatures monitoring) In contrast to the XC6805x4, the XC6805x2 does not have 10°C and 60°C monitoring, and stops charging when Thermistor Temperature ≤0°C and when Thermistor Temperature ≥ 45°C. (*3) In addition, when 0°C< Thermistor Temperature ≤ 10°C, the charge current does not change from ICHG.(*2) (*1) On the XC6805xN, battery temperature protection function in not built in. (*2) During trickle charging, the charge current is limited to ICHG× 0.1. (*3) Even when charging is stopped, tTRK count and tCHG count are continued and the charge status output pin maintains the ON state.

For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable. Please strengthen VIN and VSS wiring in particular. 3. Please mount the CIN, CL and charge current setting resistor as close to the IC as possible. 4. Do not connect anything other than a resistance for setting the charge current to the ISET pin. 5. Torex places an importance on improving our products and their reliability. We request that users incorporate fail-safe designs and post-aging protection treatment when using Torex products in their systems. 6. This IC uses an external thermistor to detect and control temperature with high accuracy. Please sufficiently test the position of the external thermistor to ensure that it enables accurate temperature detection. 7. Reversing the polarity of the battery may cause destruction and is extremely dangerous. Never reverse the polarity of the battery. 8. Short-circuiting to neighboring pins may cause malfunctioning and destruction. Exercise sufficient caution when mounting and using the IC. 9. If a large ripple voltage occurs at the VIN pin, the IC may malfunction. Please test thoroughly. 10. Taking the temperature characteristics and the dispersion into consideration, please set the charge current not to exceed the range of 5mA to 40mA. 11. If the ISET pin is shorted to the GND, there is a possibility that the IC is destroyed before the over-current monitor function is activated. 12. When VBAT is 1 V or less, the error range of the trickle charge current becomes big. When VIN – VBAT voltage is high in particular, please pay attention when using as there are possibilities that a large trickle current flows. 13.
