The SiP32431 is 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.
