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.
