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 2.8−5.5 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.
