GENERAL DESCRIPTION

The ADM1186-1 and ADM1186-2 are integrated, four-channel voltage monitoring and sequencing devices. A 2.7 V to 5.5 V power supply is required on the VCC pin for power.

Four precision comparators, VIN1 to VIN4, monitor four voltage rails. All four comparators share a 0.6 V reference and have a worst-case accuracy of 0.8. Resistor networks that are external to the VIN1, VIN2, VIN3, and VIN4 pins set the undervoltage (UV) trip points for the monitored supply rails.
