3 Description
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.
