SIP32431

SiP32431 Vishay Siliconix 1.0 A Slew Rate Controlled Load Switch with Reverse Blocking in SC70-6, and TDFN4 1.2 mm x 1.6 mm DESCRIPTION The SiP32431 is a 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 1.0 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 50 pA. 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.
