Description

The MAX16137 is a low-voltage, ±1% accurate supervisory circuit that monitors a single system supply voltage for undervoltage and overvoltage faults within a factory-set threshold window. When the monitored supply voltage drops below the undervoltage threshold or goes above the overvoltage threshold, the reset output asserts low. The reset output deasserts after the reset timeout period when the supply voltage returns to within the undervoltage and overvoltage threshold window. The reset output is active-low available in either the push-pull or open-drain options.

The MAX16137 offers factory-trimmed nominal input voltage options from 0.5V to 5V in approximately 20mV increment. A variety of factory-trimmed undervoltage/overvoltage thresholds from ±4% to ±11% are available to accommodate different supply voltages and tolerances.

The MAX16137 features a unique Built-In-Self-Test (BIST) diagnostic capability that monitors the health of the internal reset circuit during power-up. If the built-in-self-test fails, the MAX16137 asserts active-low BIST low. During normal operation, the MAX16137 performs an on-demand BIST when the active-low CLR/BIST is pulled low for more than 150μs. See the Built-In-Self-Test section for more details.

The MAX16137 is available in a small, 2mm x 2mm, 8-pin TDFN side-wettable package with exposed pad and operates over the automotive temperature range of -40°C to +125°C.
