0.3% Accuracy Dual-Channel Supervisory Circuit

The MAX16193 is an ultra-high accuracy, dual-channel window-detector supervisor circuit that monitors a system's supply rails for undervoltage and overvoltage faults. Input channel 1 (IN1) monitors low core voltage rails from a 0.6V to 0.9V threshold range with ±0.3% accuracy while input-channel 2 (IN2) monitors higher system rails from a 0.9V to 3.3V threshold range with ±0.3% accuracy. A variety of factory trimmed undervoltage/overvoltage thresholds from ±2% to ±5% are available to accommodate different supply voltages and tolerances.

The MAX16193 features two independent, active-low reset outputs. Both reset output are available in either an open-drain or push-pull version. Each reset output asserts low when the corresponding monitored rail falls outside of the undervoltage/overvoltage threshold window. The reset outputs deassert after a factory-set reset timeout period when the corresponding rail voltage returns to its nominal voltage level.

The MAX16193 is available in a small, 2mm x 3mm, 8-pin standard TDFN chip-on-lead package for industrial and a side-wettable package for automotive. It can operate over the temperature range of -40°C to +125°C.
