ADM1184/ADM1186 Voltage Monitors

±0.8% accurate quad voltage monitors from Analog Devices

Image of Analog Devices' ADM1184 ADI's ADM1184/ADM1186 are integrated, four-channel, voltage monitoring devices with the ADM1186 also providing sequencing. 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, with all comparators sharing a 0.6 V reference and a worst-case accuracy of 0.8%. Resistor networks that are external to the VIN1, VIN2, VIN3, and VIN4 pins set the under voltage (UV) trip points for the monitored supply rails. The ADM1184 has three open-drain outputs whereas the ADM1186 has four. The ADM1184 comes in a 10-pin MSOP package and has a -40C° to +85C° temperature range. The ADM1186 comes in a 16- and 20-pin QSOP package. The ADM1184/ADM1186 are ideal for telecommunications, servers, and microprocessor systems.
