07352-001 GND Figure 1. GENERAL DESCRIPTION
The ADM1184 is an integrated, 4-channel voltage-monitoring device. A 2.7 V to 5.5 V power supply is required on the VCC pin to power the device. Four precision comparators monitor four voltage rails. Each comparator has a 0.6 V reference with a worst-case accuracy of 0.8%. Resistor networks that are external to the VIN1, VIN2, VIN3, and VIN4 pins set the trip points for the monitored supply rails. The ADM1184 has four open-drain outputs. OUT1 to OUT3 can be used to enable power supplies, and PWRGD is a common power-good output. OUT1 to OUT3 are dependent on their associated VINx input (that is, VIN1, VIN2...
