TPS2114A

自动切换功率 MUX

The TPS211xA family of power multiplexers 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 2 A, depending on package. The TPS211xA 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.
