TPS2110中文资料具有手动、自动和慢速切换功能的 2.8V 至 5.5V、120mΩ、0.75A 电源多路复用器数据手册TI规格书

描述 Description

The TPS211x family of power multiplexers enables seamless transition between two power supplies, such as a battery and a wall adapter, each operating at 2.8–5.5 V and delivering up to 1 A. 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.
