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 TPS2115A-Q1 device 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.
