自动开关MUX AUTOSWITCHING POWER MUX

The is a Power Multiplexer that enables seamless transition between two power supplies such as a battery and a wall adapter, delivering up to 2A. The 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. Controlled output voltage transition times, limits inrush current and minimizes output voltage hold-up capacitance.
