The TPS7H2221-SEP device is a 5.5-V, 1.25-A load switch in a 6-pin SOT-23 package. To reduce voltage drop for low voltage and high current rails, the device implements a low resistance N-channel MOSFET that reduces the drop out voltage across the device.

The TPS7H2221-SEP device has a slow slew rate, which helps reduce or eliminate power supply droop because of large inrush currents during power up. Furthermore, the device features a Quick-Output-Discharge (QOD) pin, which allows the configuration of the discharge rate of V_OUT once the switch is disabled. During shutdown, the device has very low leakage currents, thereby reducing unnecessary leakages for downstream devices during standby. Integrated control logic, driver, charge pump, and output discharge FET eliminates the need for any external components, which reduces solution size and bill of materials (BOM) count.

The TPS7H2221-SEP load switch is also self-protected, meaning that it will protect from short circuit events on the output of the device. It also has thermal shutdown to prevent thermal runaway.
