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.
