Product details

130 mA load switch with integrated fault protection

The part integrates fixed current limiting, over-temperature shutdown, and reverse current protection, reducing the need for discrete protection components on the board.

Protection features that simplify the BOM

Three built-in fault protections — fixed current limiting, over-temperature shutdown, and reverse current blocking — cover the common failure modes in power-rail sequencing and hot-swap applications. The reverse current protection is particularly relevant when the load side holds a charged capacitor or battery and the input rail collapses, preventing back-feed into the upstream supply. The auto-restart feature (listed under Features) means the switch attempts to re-enable after a fault condition clears, rather than latching off. This suits applications where temporary overcurrent events are expected, such as powering a capacitive load or a sensor that draws inrush at startup.

Frequently asked questions

Does TPS22948DCKR have reverse current protection?

Yes, reverse current protection is listed among the fault protection features. When the output voltage exceeds the input, the switch blocks reverse current flow, preventing back-feed into the supply rail.

What is the maximum output current for TPS22948DCKR?

The maximum continuous output current is 130 mA.
