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.
