DESCRIPTION

The TPS211xA family of power multiplexers enables

seamless transition between two power supplies,

such as a battery and a wall adapter, each operating

at 2.8 V to 5.5 V and delivering up to 1 A. The

TPS211xA 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.
