MAX6324
MAX6324 is uP Supervisory manufactured by Maxim Integrated.
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 lasertrimmed reset thresholds are available with ±2.5% accuracy from +2.32V to +4.63V. Valid RESET output is guaranteed down to VCC = +1.2V. The RESET output is either push-pull (MAX6323) or open-drain (MAX6324). RESET is asserted low when VCC falls below the reset threshold, or when the manual reset input (MR) is asserted low. RESET remains asserted for at least 100ms after VCC rises above the reset threshold and MR is deasserted.
The watchdog pulse output (WDPO) utilizes an opendrain configuration. It can be triggered either by a fast timeout fault (watchdog input pulses are too close to each other) or a slow timeout fault (no watchdog input pulse...
