General Description

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.
