Texas Instruments  PTPS22919QDCKRQ1

The TPS22919-Q1 device is a small, single channel load switch with controlled slew rate.The device contains an N-channel MOSFET that can operate over an input voltage range of 1.6 V to5.5 V and can support a maximum continuous current of 1.5 A.

The switch ON state is controlled by a digital input that is capable of interfacingdirectly with low-voltage control signals. When power is first applied, a Smart Pull Down is usedto keep the ON pin from floating until system sequencing is complete. Once the pin is deliberatelydriven High (>VIH), the Smart Pull Down will be disconnected to preventunnecessary power loss.

The TPS22919-Q1 load switch is also self-protected, meaning that it will protect itselffrom short circuit events on the output of the device. It also has thermal shutdown to prevent anydamage from overheating.

TPS22919-Q1 is available in a standard SC-70 package characterized for operation over ajunction temperature range of –40°C to 125°C.
