Description
The MAX6369–MAX6374 are flexible watchdog timer supervisors that can increase system reliability through notification of code execution errors. The family offers several pin-selectable watchdog timing options to match a wide range of system timing applications:
- Watchdog startup delay: provides an initial delay before the watchdog timer is started.
- Watchdog timeout period: normal operating watchdog timeout period after the initial startup delay.
- Watchdog output/timing options: open drain (100ms) or push-pull (1ms).
