Update: 01 October, 2023
The MAX6381-MAX6390 microprocessor (µP) supervisory circuits monitor power supply voltages from +1.8V to +5.0V while consuming only 3µA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains assert- ed for a minimum reset timeout period after VCC rises above the reset threshold. Reset thresholds are available from +1.58V to +4.63V, in approximately 100mV incre- ments. Seven minimum reset timeout delays ranging from 1ms to 1200ms are available. The MAX6381/MAX6384/MAX6387 have a push-pull active-low reset output. The MAX6382/MAX6385/ MAX6388 have a push-pull active-high reset output, and the MAX6383/MAX6386/MAX6389/MAX6390 have an open-drain active-low reset output. The MAX6384/MAX6385/MAX6386 also feature a debounced manual reset input (with internal pullup resistor). The MAX6387/MAX6388/MAX6389 have an auxiliary input for monitoring a second voltage. The MAX6390 offers a manual reset input with a longer VCC reset timeout period (1120ms or 1200ms) and a shorter manual reset timeout (140ms or 150ms). The MAX6381/MAX6382/MAX6383 are available in 3-pin SC70 packages and the MAX6384–MAX6390 are avail- able in 4-pin SC70 packages.
