DESCRIPTION

The TPS211x family of power multiplexers enables seamless transition between two power supplies, such as a

battery and a wall adapter, each operating at 2.8-5.5 V and delivering up to 1 A. The TPS211x family includes

extensive protection circuitry, including user-programmable current limiting, thermal protection, inrush current

control, seamless supply transition, cross-conduction blocking, and reverse-conduction blocking. These features

greatly simplify designing power multiplexer applications.
