DESCRIPTION/ORDERING INFORMATION

The TPS2115A power multiplexer enables seamless transition between two power supplies, such as a battery and a wall adapter, each operating at 2.8 V to 5.5 V and delivering up to 1 A. The TPS2115A 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.
