The TPS22948 device is a small, single channel load switch with robust protection against fault cases with output current limiting, reverse current blocking, and thermal shutdown.

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 pin is deliberately driven high (>VIH), the smart pull down will be disconnected to prevent unnecessary power loss. ™

TPS22948 is available in a standard SC-70 package characterized for operation over a temperature range of –40°C to 125°C.
