USB Type-C and other hot-swap applications. Through the analog
interface, exception status is reported and functions like voltage
limiting and output voltage ramp-up rate can be programmed.

This device is designed to operate between 4.5V and 24V. Its built-in
fault-handling mechanism includes reverse voltage and current
blocking, input over-voltage protection, and thermal shutdown. In
addition, the ramp-up time of the output voltage can be adjusted to
minimize in-rush current and to ensure system stability. Before any
exception condition is notified via the low-active FAULTB signal, de-
glitch of 7ms is applied to prevent false triggering.
