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.
