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.
