描述

The MAX16191 is a single-channel, ultra-high accuracy supervisor circuit that monitors 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 deasserts after reset timeout period when the monitored supply voltage falls within the threshold window. The reset output is active-low and available in open-drain or push-pull configuration.

The MAX16191's nominal input voltage level is factory-programmable to any voltage between 0.6V to 0.9V. Together with the ±2% to ±5% undervoltage/overvoltage window threshold range, the MAX16191 offers the flexibility to monitor a wide range of system supply voltages. The undervoltage/overvoltage threshold levels are factory programmable and are symmetrical with respect to the nominal input voltage setting.

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