- Ultra-low leakage and quiescent current
- No bias power rail required
- Soft switching to minimize turn on in rush current
- Reverse blocking at switch off state
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.
