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.
