3 Description

The TPS22918 is a single-channel load switch with

configurable rise time and configurable quick output

discharge. The device contains an N-channel

MOSFET that can operate over an input voltage

range of 1 V to 5.5 V and can support a maximum

continuous current of 2 A. The switch is controlled by

an on and off input, which is capable of interfacing

directly with low-voltage control signals.

The configurable rise time of the device greatly

reduces inrush current caused by large bulk load

capacitances, thereby reducing or eliminating power

supply droop. The TPS22918 features a configurable

quick output discharge (QOD) pin, which controls the

fall time of the device to allow design flexibility for

power down and sequencing.

The TPS22918 is available in a small, leaded SOT-23

package (DBV) which allows visual inspection of

solder joints. The device is characterized for

operation over the free-air temperature range of

–40°C to +105°C.
