SIP32414

SiP32413, SiP32414 Vishay Siliconix Dual 2 A, 1.2 V, Slew Rate Controlled Load Switch DESCRIPTION SiP32413 and SiP32414 are slew rate controlled load switches that is designed for 1.1 V to 5.5 V operation. The devices guarantee low switch on-resistance at 1.2 V input. They feature a controlled soft-on slew rate of typical 150 µs that limits the inrush current for designs of capacitive load or noise sensitive loads. The devices feature a low voltage control logic interface (On/ Off interface) that can interface with low voltage digital control without extra level shifting circuit. The SiP32414 also integrates output discharge switches that enable fast shutdown load discharge. When the switches are off, they provide the reverse blocking to prevent high current flowing into the power source. Both the SiP32413 and SiP32414 are available in TDFN8 2 mm x 2mm package. Each switch in each device can support over 2 A of continuous current.

Once enable the device charge pumps the gate of the power MOSFET to 5 V gate to source voltage while controlling the slew rate of the turn on time. The mostly constant gate to source voltage keeps the on resistance low through out the input voltage range. For SiP32414, when disable the output discharge circuit turns on to help pull the output voltage to ground more quickly. For both parts, in disable mode, the reverse blocking circuit is activated to prevent current from going back to the input in case the output voltage is higher than the input voltage. Input voltage is needed for the reverse blocking circuit to work properly, it can be as low as VIN(min). package. To obtain the highest power dissipation (and a thermal resistance of 84) the power pad of the device should be connected to a heat sink on the printed circuit board. The maximum power dissipation in any application is dependant on the maximum junction temperature, TJ(max.) = 125 °C, the junction-to-ambient thermal resistance for the TDFN4 1.2 mm x 1.6 mm package, θJ-A = 84 °C/W, and the ambient temperature, TA, which may be formulaically expressed as: P (max.) = T J (max.) - T A θJ- A = 125 - TA 84 APPLICATION INFORMATION Input Capacitor While bypass capacitors on the inputs are not required, 2.2 µF or larger capacitors for CIN is recommended in almost all applications. The bypass capacitors should be placed as physically close as possible to the device’s input to be effective in minimizing transients on the input. Ceramic capacitors are recommended over tantalum because of their ability to withstand input current surges from low impedance sources such as batteries in portable devices. Output Capacitor A 0.1 µF capacitor or larger across VOUT and GND is recommended to insure proper slew operation. COUT may be increased without limit to accommodate any load transient condition with only minimal affect on the turn on slew rate time. There are no ESR or capacitor type requirement. Control The CNTRL pins are compatible with both TTL and CMOS logic voltage levels. Protection Against Reverse Voltage Condition Both SiP32413 and SiP32414 contain reverse blocking circuitries to protect the current from going to the input from the output in case where the output voltage is higher than the input voltage when the main switch is off. Supply voltages as low as the minimum required input voltage are necessary for these circuitries to work properly. Thermal Considerations SiP32413 and SiP32414 are designed to maintain constant output load current. Due to physical limitations of the layout and assembly of the device the maximum switch current is 2.4 A, as stated in the Absolute Maximum Ratings table. However, another limiting characteristic for the safe operating load current is the thermal power dissipation of the It then follows that, assuming an ambient temperature of 70 °C, the maximum power dissipation will be limited to about 655 mW. So long as the load current is below the 2.0 A limit, the maximum continuous switch current becomes a function two things: the package power dissipation and the RDS(ON) at the ambient temperature. As an example let us calculate the worst case maximum load current at TA = 70 °C. The worst case RDS(ON) at 25 °C occurs at an input voltage of 1.2 V and is equal to 75 mΩ. The RDS(ON) at 70 °C can be extrapolated from this data using the following formula: RDS(ON) (at 70 °C) = RDS(ON) (at 25 °C) x (1 + TC x ΔT) Where TC is 3400 ppm/°C. Continuing with the calculation we have RDS(ON) (at 70 °C) = 75 mΩ x (1 + 0.0034 x (70 °C - 25 °C)) = 86.5 mΩ The maximum current limit is then determined by P (max.) I LOAD (max.) < R DS(ON ) which in case is 2.75 A, assuming one switch turn on at a time. Under the stated input voltage condition, if the 2.75 A current limit is exceeded the internal die temperature will rise and eventually, possibly damage the device.
