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.
