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.
