Detailed Description
The MAX6369–MAX6374 are pin-selectable watchdog timers that supervise microprocessor (μP) activity and signal when a system is operating improperly.
During normal operation, the microprocessor should repeated- ly toggle the watchdog input (WDI) before the selected watchdog timeout period elapses to demonstrate that the system is processing code properly.
If the μP does not provide a valid watchdog input transition before the timeout period expires, the supervisor asserts a watch- dog (WDO) output to signal that the system is not exe- cuting the desired instructions within the expected time frame.
The watchdog output pulse can be used to reset the μP or interrupt the system to warn of processing errors.
