TPS22980 Overview
The TPS22980 is a current-limited power mux providing a connection to a peripheral device from either a low voltage supply (3.0V up to 3.6V) or a high voltage supply (5V up to 18V). The desired output is selected by digital control signals. The high voltage (VHV) and low voltage (V3P3) switch current limits are set with external resistance.
