TPS22981 Description
The TPS22981 device is a current-limited power mux providing a connection to a peripheral device from either a low-voltage supply (3 V to 3.6 V) or a highvoltage supply (4.5 V to 19.8 V). 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.
