3 Description

The TPS2115A-Q1 power multiplexer enables

seamless transition between two power supplies,

such as a two supply rails or a battery and AC to DC

wall adapter. Each supply operates at 2.8 V to 5.5 V

and the output can deliver up to 1 A. The TPS2115AQ1

device includes extensive protection circuitry

including user-programmable current limiting, thermal

protection, inrush current control, seamless supply

transition, cross-conduction blocking, and reverseconduction

blocking. These features greatly simplify

designing power multiplexer applications.
