Image of Texas Instruments' TPS22919 Load Switch Texas Instruments' TPS22919 device is a small, single-channel load switch with a controlled slew rate. The device contains an N-channel MOSFET that can operate over an input voltage range of 1.6 V to 5.5 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 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 the system sequencing is complete. Once the pin is deliberately driven high (>V_IH), the smart pull-down will be disconnected to prevent unnecessary power loss.

The TPS22919 load switch will protect itself from short-circuit events on the output. The converter has thermal shutdown to prevent any damage from overheating. The TPS22919 is available in a standard SC-70 package characterized for operation over a junction temperature range of -40°C to +125°C.
