The TPS22946YZPR is an ultralow power Load Switch that provides protection to systems and loads in high-current conditions. The device contains a 300mR current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 to 5.5V. The switch is controlled by an on/off input (ON), which can interface directly with low-voltage control signals. The TPS22946 includes thermal shutdown protection that prevents damage to the device when a continuous over-current condition causes excessive heating by turning off the switch. When the switch current reaches the maximum limit, the TPS22946 operates in a constant-current mode to prohibit excessive currents from causing damage. The TPS22946 has an auto-restart feature which turns the switch on again after 70ms if the ON pin is still active. If the TPS22946 remains in an over-current condition for 5 seconds, the device shuts off until it is turned on again by setting the ON control signal off and then on.
