Texas Instruments TPS2112 Dual In/Single Out Autoswitching Power MUX, Auto Sw, Adj. Cur Limit, Adj. Vol Threshold, Sw Status TPS2112PWRG4

The TPS2112PWRG4 is a dual input, single output power multiplexer designed for seamless transitions between two power sources, such as a battery and a wall adapter, operating within a voltage range of 2.8 V to 5.5 V and capable of delivering up to 0.9 A. It features low on-resistance switches with a typical value of 120 m,Ѷ, adjustable current limit, and controlled output voltage transition times to minimize inrush current and output voltage hold-up capacitance. The device includes protection features such as thermal shutdown, reverse and cross-conduction blocking, and low standby current of 0.5 µA. It is compatible with CMOS and TTL control inputs and is housed in a TSSOP-8 package, making it suitable for various applications including PCs, digital cameras, and cell phones.
