9.4.1 NORMAL Mode

When COUT and DOUT are inactive (no fault detected) the device operates in NORMAL mode and device is monitoring for voltage, open wire and temperature faults.

The COUT and DOUT pins are inactive and if configured:

  • Active high is low.
  • Active low is being externally pulled up and is an open drain.
