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.
