Product details

Load switch with 8.7 mOhm on-resistance — what it buys you

Its typical Rds(on) of 8.7 mOhm keeps conduction loss low at the 6 A maximum continuous output.

Input range, control, and protection

The On/Off interface is non-inverting and the output is an N-channel MOSFET configured as a high-side switch with a 1:1 input-to-output ratio. Built-in fault protection includes fixed current limiting and over-temperature shutdown — no external sense resistor or thermistor needed.

Slew-rate control and temperature grade

Slew-rate controlled switching reduces inrush current and supply droop when the load is connected, a useful feature for powering capacitive loads like sensor modules or radio front-ends.

Frequently asked questions

What is the Rds(on) of the TPS22992SRXNR?

The typical Rds(on) is 8.7 mOhm, specified at the operating condition in the datasheet. This is the conduction-loss figure to use for thermal budgeting at the 6 A maximum output.

Does the TPS22992SRXNR have overcurrent protection?

Yes, it includes fixed current limiting and over-temperature shutdown as built-in fault protection.
