3 Description

The TPS22917 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 unneccesary 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 fasest fall time or leave it

open for the slowest fall time.

The switch ON state is controlled by a digital input

that is capable of interfacing 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 (

≥VIH), the Smart Pull

Down is disconnected to prevent unnecessary power

loss.

The TPS22917 is available in a small, leaded SOT-23

package (DBV) which allows visual inspection of

solder

joints.

is

characterized

for

operation over a temperature range of –40°C to

+105°C.
