This IC can supervise any positive voltage using an external resistor divider to translate to a lower voltage for parison to the internal 0.633V reference. Once any VMON input falls below 0.633V the PGOOD output is pulled low, the hysteresis of the internal reference is 15m V. The PGOOD pin has an internal 20k W pull-up to VCC making an external pull-up resistor unnecessary.

The PGOOD output is guaranteed to be valid with IC bias lower than 1V. This IC is designed to reject fast line transient glitches 30ms on VMON input. The PGOOD output is an openhttp://../ drain to allow ORing of multiple signals. If less than four voltages are being monitored, connect the unused VMON pins to VCC. The ENABLE input pin provides for a reset of the PGOOD output when it is pulled down below 0.5V.
