3 Description

The TPS22918-Q1 is a single-channel load switch

with both 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 reduces

inrush

current

caused

by

large

bulk

load

capacitances, thereby reducing or eliminating power

supply

droop.

The

TPS22918-Q1

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-Q1 is available in a small, leaded

SOT-23 package (DBV) which allows to visually

inspect solder joints. The device is characterized for

operation over the free-air temperature range of

–40°C to +105°C.
