DESCRIPTION

The SiP32431 and SiP32432 are ultra low leakage and

quiescent current slew rate controlled high side switches

with reverse blocking capability. The switches are of a low

ON resistance p-channel MOSFET that supports continuous

current up to 1.4 A.

The SiP32431 and SiP32432 operate with an input voltage

from 1.5 V to 5.5 V.

The SiP32431 and SiP32432 feature low input logic level to

interface with low control voltage from microprocessors.

The SiP32431 is of logic high enable control, while SiP32432

is of logic low enable control. Both devices have a very low

operating current, typically 10 pA at 3.3 V power supply.

The SiP32431 and SiP32432 are available in lead (Pb)-free

package options including 6 pin SC-70-6, 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 and SiP32432 compact package options,

operation voltage range, and low operating current make it

a good fit for battery power applications.
