Description
General part information
TPS22980 Series
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. Once the current limit is reached, the TPS22980 will control the switch to maintain the current at the limit.
When the high voltage supply is not present, the TPS22980 will maintain the connection to the output from the low voltage supply. When a high voltage line and high voltage enable signal is detected by the device, the high voltage switch will be turned on in conjunction with the low voltage switch until a reverse current is detected by the low voltage switch. The low voltage switch is then disabled allowing a seamless transition from a low voltage to a high voltage supply with minimal drop and shoot-through current.
