General Description

The MAX6323/MAX6324 microprocessor (µP) supervisory circuits monitor power supplies and µP activity in digital systems. A watchdog timer looks for activity outside an expected window of operation. Six laser-trimmed reset thresholds are available with ±2.5 accuracy from +2.32V to +4.63V. Valid RESET output is guaranteed down to VCC = +1.2V.
