Fig. 3 Example circuit when power down is maintained by external controller.

2.3 I/O circuit for /FAULT pin

resistor is from 15K .

voltage is used for the pin, the voltage should be divided not to get damaged by electrical overstress. Fig. 5 shows the example configuration of a voltage divider using resistors.
