3 Description

The TPS22917 device is a small, single channel load

switch utilizing a low leakage P-Channel MOSFET for

minimum power loss. Advanced gate control design

supports operating voltages as low as 1 V with

minimal increase in ON-Resistance and power loss.

The Rise and Fall times can be independently

adjusted with external components for system level

time can be adjusted to manage inrush current

without adding unnecessary system delays. The

output discharge resistance (QOD) can be used to

adjust the output fall time. Connect the QOD pin

directly to the output for a fastest fall time or leave it

open for the slowest fall time.

The switch ON state is controlled by a digital input

that can interface directly with low-voltage control

signals. When power is first applied, a Smart Pull

Down is used to keep the ON pin from floating until

system sequencing is complete. Once the ON pin is

deliberately driven high (
