MAX6369KA+ - Brand New Maxim Integrated Supervisors
-
Description
Electronic Component Model: MAX6369KA+
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 repeatedly 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 executing 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.

Application Scenarios
This electronic component model can be used in microprocessor applications where the proper execution of instructions is crucial. It is particularly useful in critical systems where the system must be monitored for any operating issues or faults. The pin-selectable watchdog timeout periods and startup delay periods allow for flexibility in configuring the system's monitoring parameters. The ability to change the watchdog timing characteristics without power cycling simplifies system maintenance and updates. The compact SOT23 package makes it suitable for space-constrained designs.
