They incorporate a negative charge pump at the gate to keep the gate to source voltage high when turned on. This keeps the on resistance low at lower input voltages. SiP32460 and SiP32461 are designed with slow slew rate to minimize inrush current during turn on. These devices have a reverse blocking circuit, when disabled, to prevent the current from going back to the input when the output voltage is higher than the input voltage. The SiP32460 and SiP32462 can be used as bidirectional switches and can be turned on and off when power is at either in or out. The SiP32461 has an output pulldown resistor to discharge the output capacitance when the device is off. APPLICATION INFORMATION Input Capacitor While a bypass capacitor on the input is not required, a 4.7 μF or larger capacitor for CIN is recommended in almost all applications. The bypass capacitor should be placed as physically close as possible to the input pin 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 across VOUT and GND is recommended to insure proper slew operation. There is inrush current through the output MOSFET and the magnitude of the inrush current depends on the output capacitor, the bigger the COUT the higher the inrush current. There is no ESR or capacitor type requirement. Enable The EN pin is compatible with CMOS logic voltage levels. It requires at least 0.4 V or below to fully shut down the device and 1 V or above to fully turn on the device. There is a 2.6 M resistor connected between EN pin and GND pin. Protection Against Reverse Voltage Condition This device contains a reverse blocking circuit. When disabled (VEN less than 0.4 V) this circuit keeps the output current from flowing back to the input when the output voltage is higher than the input voltage. Thermal Considerations Due to physical limitations of the layout and assembly of the device the maximum switch current is 1.2 A as stated in the Absolute Maximum Ratings table. However, another limiting S20-0532-Rev. E, 06-Jul-2020 characteristic for the safe operating load current is the thermal power dissipation of the package. The maximum power dissipation in any application is dependent on the maximum junction temperature, TJ(max.) = 125 °C, the junction-to-ambient thermal resistance, J-A = 205 °C/W, and the ambient temperature, TA, which may be expressed as: 125 - T A T J(max.) - T A P (max.) = -------------------------------- = ---------------------- JA 205 It then follows that, assuming an ambient temperature of 70 °C, the maximum power dissipation will be limited to about 268 mW. So long as the load current is below the 1.2 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 is 120 m at VIN = 1.5 V. The RDS(on) at 70 °C can be extrapolated from this data using the following formula: RDSon) (at 70 °C) = RDS(on) (at 25 °C) x (1 + TC x T) Where TC is 2800 ppm/°C. Continuing with the calculation we have RDS(on) (at 70 °C) = 120 m x (1 + 0.0028 x (70 °C - 25 °C)) = 135 m The maximum current limit is then determined by P (max.) I LOAD(max.)  --------------------R DS(on) which in this case is 1.99 A. Under the stated input voltage condition, if the 1.99 A current limit is exceeded the internal die temperature will rise and eventually, possibly damage the device. To avoid possible permanent damage to the device and keep a reasonable design margin, it is recommended to operate the device maximum up to 1.2 A only as listed in the Absolute Maximum Ratings table.     Document Number: 67754 12 For technical questions, contact: powerictechsupport@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
