12-Channel/8-Channel EEPROM-Programmable
System Managers with Nonvolatile Fault Registers
Any_Fault Outputs
GPIO1–GPIO4 are configurable as active-low push-pull
or open-drain fault-dependent outputs. These outputs
assert when any monitored input exceeds an overvolt-
age, undervoltage, or early warning threshold.
FAULT1 and FAULT2
GPIO5 and GPIO6 are configurable as dedicated fault
outputs, FAULT1 and FAULT2, respectively. Fault
outputs can assert on one or more overvoltage, under-
voltage, or early warning conditions for selected inputs.
FAULT1 and FAULT2 dependencies are set using reg-
isters r15h to r18h. See Table 7.
If a fault output depends on more than one MON_, the
fault output will assert if one or more MON_ exceeds a
programmed threshold voltage.
