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.
