Vishay introduces the SiP32431 an ultra low leakage and quiescent current slew rate controlled high side switch with reverse blocking capability. The switch is of a low ON resistance p-channel MOSFET that supports continuous current up to 1 A. The SiP32431 operates with an input voltage from 1.5 V to 5.5 V. The SiP32431 features low Input logic level to interface with low control voltage from microprocessors.

This device has a very low operating current, typically 10 pA at 3.3 V power supply. The SiP32431 is available in lead (Pb)-free package options including 6 pin SC70-6, and 4 pin TDFN4 1.2 mm x 1.6 mm DFN4 packages. The operation temperature range is specified from -40 °C to +85 °C. The SiP32431 compact package options, operation voltage range, and low operating current make it a good fit for battery power applications.
