GENERAL DESCRIPTION

VIN4

The ADM1185 is an integrated four channel voltage monitoring

device. A 2.7V to 5.5V power supply is required on the VCC pin

to power the device.

PWRGD

Four precision comparators monitor four voltage rails. All

comparators have a 0.6V reference with a worst-case accuracy

of 0.8%. Resistor networks external to the VIN1-VIN4 pins set

the trip points.

GND

Figure 1.

There are four open-drain outputs on the device. A digital core

interprets the comparator outputs and asserts the outputs as

appropriate.
