3 Description

The TPS22924D is a small, low RON load switch with controlled turn on. The device contains a N-channel

MOSFET that can operate over an input voltage

range of 0.75 V to 3.6 V. An integrated charge pump

biases the NMOS switch to achieve a minimum

switch ON resistance. The switch is controlled by an on/off input (ON), which is capable of interfacing

directly with low-voltage control signals.

A 1250 Ω on-chip load resistor is added for output

quick discharge when the switch is turned off. The

rise time of the device is internally controlled to avoid

inrush current. The TPS22924D features a rise time

of 6200 μs at 3.6 V.

The TPS22924D is available in an ultra-small, spacesaving

6-pin CSP package and is characterized for

operation over the free-air temperature range of

–40ºC to 85ºC.
