TPS2111PWG4

TEXAS INSTRUMENTS  TPS2111PWG4  自动切换电源多路复用器, 双路输入, 高压侧, 高电平有效, 1路输出, 5.5V, 1.25A, TSSOP-8

The is a 2-input 1-output Power Multiplexer enables seamless transition between two power supplies, such as a battery and a wall adapter, each operating at 2.8 to 5.5V and delivering up to 1A. The TPS211x 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. Controlled output voltage transition times, limits inrush current and minimizes output voltage hold-up capacitance.
