Supply voltages assessed by supervisor circuit
The MAX16191 from Maxim Technology 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 the reset timeout period when the monitored supply voltage falls within the threshold window. It 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 0.6 V to 0.9 V.
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 2 mm x 2 mm 8-pin TDFN side-wettable package and operates over the automotive temperature range of -40°C to +125°C.
Applications include automotive, ADAS and multivoltage ASICs.
