Description

The ADM1184 series 4-channel integrated Voltage Monitoring Device with 4 open-drain outputs. OUT1 to OUT3 can be used to enable power supplies and PWRGD is a common power-good output indicating that all monitored supplies are above their respective thresholds. OUT1 to OUT3 are dependent on their associated VINx input (that is, VIN1, VIN2 or VIN3). If a supply monitored by VINx drops below its programmed threshold, the associated OUTx pin and PWRGD are disabled. A 2.7 to 5.5V power supply is required on the VCC pin to power the device. Four precision comparators monitor four voltage rails. Each comparator has a 0.6V 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. PWRGD is a common power-good output indicating the status of all monitored supplies. There is an internal 190ms (typical) delay associated with the assertion of the PWRGD output.

4 Inputs can be programmed to monitor different voltage levels with external resistor dividers
3 Open-drain enable outputs (OUT1, OUT2 and OUT3)
Open-drain power-good output (PWRGD)
Internal 190ms delay associated with assertion of PWRGD
