The TPS22992 and TPS22992S devices are both single-channel load switches with an 8.7-mΩ power MOSFET designed to operate up to 6 A. The voltage range of the TPS22992 device is 0.1 V to 5.5 V, and the voltage range of the TPS22992S device is 1 V to 5.5 V. A configurable rise time provides flexibility for power sequencing and minimizes inrush current for high capacitance loads.

The switch is controlled by an enable pin (ON), which is capable of interfacing directly with low voltage GPIO signals down to its V_IH level of 0.8 V. The TPS22992x device has an optional QOD pin for quick output discharge when switch is turned off, and the fall time (t_FALL) of the output can be adjusted through an external resistor. There is a Power Good (PG) signal on the device that indicates when the main MOSFET is fully turned on and the on-resistance is at its final value.

Both TPS22992x devices come with thermal shutdown to ensure protection in high temperature environments. The TPS22992S also integrates overcurrent protection, preventing damage to the device if the output is shorted to ground during operation or start-up.
