Power Distribution Switches, Load Drivers FAQ

What is the function of the fault report pin?

The fault report pin signals when the device has triggered a protection event, such as overcurrent or thermal shutdown, allowing the system to monitor health status.

How does the device handle power insertion?

It controls the ramp-up of voltage to the load using the internal MOSFET, preventing inrush currents that could damage the bus or connected components during hot-plug events.
