Pull-up Resistor on FAULT Pin

The FAULT pin is an open collector output and therefore

requires a pull-up resistor to provide a high-level signal.

Also the FAULT output can be wire ‘OR’ed together with

other types of protection (e.g. over-temperature, over-

voltage, over-current ) to alert the microcontroller.
