Key ratings and what they mean for the BOM
Internal switches are included — no external MOSFET needed. The controller handles the turn-on ramp, fault detection, and latching. The fault timeout and latched fault behaviour means that after a sustained overcurrent event, the channel shuts off and stays off until the input is cycled or the fault is cleared, which protects the USB host from a shorted peripheral.
Lifecycle and sourcing posture
