The Auto Restart feature re-tries the output after an over-temperature fault clears, which is useful for intermittent overloads. Load Discharge pulls the output to ground when the switch is turned off, preventing floating rails during power-down sequencing. A Power Good output gives a logic-high signal when the output is within regulation — handy for cascading into a downstream converter's enable pin or for a microcontroller GPIO to poll.","metaTitle":"TPS22954DSQR load switch, 14 mOhm, 5 A, active","metaDescription":"Texas Instruments TPS22954DSQR high-side load switch: 14 mOhm Rds(on), 5 A max, 2.5-5.7 V input, -40 to 105°C, active lifecycle.
