Overview
- Powered from 2.7 V to 5.5 V on the VCC pin
- 4 inputs can be programmed to monitor different voltage levels with external resistor dividers
- 3 open-drain enable outputs (OUT1, OUT2, and OUT3)
- 10-lead MSOP
- Open-drain power-good output (PWRGD)
- Internal 190 ms delay associated with assertion of PWRGD
- Monitors 4 supplies via 0.8% accurate comparators
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. Of these 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.
PWRGD is a common power-good output indicating the status of all monitored supplies. There is an internal 190 ms (typical) delay associated with the assertion of the PWRGD output. If VIN1, VIN2, VIN3, or VIN4 drops below its programmed threshold, PWRGD is deasserted immediately.
The ADM1184 is available in a 10-lead mini small outline package (MSOP).
