The TPS2117 is a power mux device with a voltage rating of 1.6 V to 5.5 V and a maximum current rating of 4 A. The device uses N-channel MOSFETs to switch between supplies while providing a controlled slew rate when voltage is first applied.

Due to its low quiescent of 1.32 µA (typical) and low standby current of 50 nA (typical), the TPS2117 is ideal for systems where a battery is connected to one of the inputs. These low currents extend the life and operation of the battery when in use.

The TPS2117 can be configured for two different switchover behaviors depending on the application. Automatic priority mode prioritizes the supply connected to VIN1 and switches over to the secondary supply (VIN2) when VIN1 drops. Manual mode allows the user to toggle a GPIO or enable signal to switch between channels.
