Analog Devices / Maxim Integrated MAX16191 Supervisory Circuit

Analog Devices MAX16191 Supervisory Circuit is a single-channel, ultra-high 0.35% accuracy supervisor circuit designed to monitor low core system supply voltages. The reset output asserts when the monitored supply voltage falls outside of the factory-trimmed undervoltage/overvoltage threshold window. The reset output de-asserts after the reset timeout period when the monitored supply voltage falls within the threshold window. The reset output is active-low and offers an open-drain or push-pull configuration. Analog Devices MAX16191 Supervisory Circuit nominal input voltage level is factory programmable to any voltage between 0.6V to 0.9V. The MAX16191 offers the flexibility to monitor a wide range of system supply voltages with the ±2% to ±5% undervoltage/overvoltage window threshold range. The undervoltage/overvoltage threshold levels are factory programmable and are symmetrical with respect to the nominal input voltage setting.

The MAX16191 has an automotive temperature range of -40°C to +125°C and is available in a small, 2mm x 2mm, 8-pin TDFN side-wettable package.
