The ADM1185ARMZ-1 from Analog Devices is an integrated, 4-channel voltage monitoring and sequencing device designed for power supply supervision and control. It requires a VCC supply voltage ranging from 2.7 V to 5.5 V.
This device utilizes four precision comparators, each with a 0.6 V reference and a worst-case accuracy of 0.8%, to monitor different voltage rails. The trip points for these monitored supplies are set using external resistor networks. A digital core within the ADM1185 interprets the comparator outputs and provides power supply sequencing capabilities with internal timeouts. It also offers fault protection, disabling outputs when supplies fall out of range.
The ADM1185ARMZ-1 features three open-drain enable outputs and one open-drain power-good (PWRGD) output, which indicates the status of all monitored supplies. This makes it suitable for applications such as monitor and alarm functions, power supply sequencing, and in telecommunication, data communication, PC, and server equipment.
Packaged in a 10-lead MSOP, the ADM1185ARMZ-1 is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C.
