The device has 66 m resistance and operates over the input voltage range of 0.9 V to 2.5 V without requirement of extra bias power rail. This device is designed to maintain a constant output load current. 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 characteristic for the safe operating load current is the thermal power dissipation of the package and the PCB layout. To obtain the highest power dissipation (and a thermal resistance of 170 °C/W) the device should be connected to a heat sink on the printed circuit board. The SiP32501 consisted of an n-channel power MOSFET designed as high side load switch. Once enabled the device charge pumps the gate of the power MOSFET to a constant gate to source voltage for fast turn on time. The mostly constant gate to source voltage keeps the on resistance low through the input voltage range. The SiP32501 features an output discharge circuit to help discharge the output capacitor. Because the body of the output n-channel is always connected to GND, it prevents the current from going back to the input in case the output voltage is higher than the input. The SiP32501 has low input logic control threshold that can interface with low voltage control GPIO directly without extra level shift or driver. The switch supports designs when control logic voltage is higher than input power voltage. There is a pull down at this EN logic control pin. 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 = 170 °C/W, and the ambient temperature, TA, which may be formulaically expressed as: 125 - T A T J (max.) - T A P (max.) = ------------------------------------- = ---------------------- JA 170 It then follows that, assuming an ambient temperature of 70 °C, the maximum power dissipation will be limited to about 323 mW. The SiP32501 has 20 μs typically for input voltage of 1.2 V. Its turn off delay time is less than 1 μs. An output discharge switch is integrated. 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. APPLICATION INFORMATION 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 82 m. The RDS(on) at 70 °C can be extrapolated from this data using the following formula: Input Capacitor While a bypass capacitor on the input is not required, to minimize the voltage drop on the input supply caused by load transient, a CIN is recommended to be placed close to IN pin. A ceramic capacitor is recommended because of their ability to withstand current surges. 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 are no ESR or capacitor type requirement. Enable The EN pin is compatible with CMOS logic voltage levels. It requires at least 0.1 V or below to fully shut down the device and 1.5 V or above to fully turn on the device. The EN pin can withstand voltage higher than VIN. Protection Against Reverse Voltage Condition SiP32501 can block the output current from going to the input in case where the output voltage is higher than the input voltage when the main switch is off. S20-0532-Rev. C, 06-Jul-2020 RDS(on) (at 70 °C) = RDS(on) (at 25 °C) x (1 + TC x T) Where TC is 4100 ppm/°C. Continuing with the calculation we have RDS(on) (at 70 °C) = 82 m x (1 + 0.0041 x (70 °C - 25 °C)) = 97.1 m The maximum current limit is then determined by P (max.) I LOAD (max.)  --------------------R DS(on) which in this case is 1.82 A. Under the stated input voltage condition, if the 1.82 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: 75595 8 For technical questions, contact: powerictechsupport@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
