The watchdog timeout period of the MAX6301 can be adjusted via an external capacitor. Please refer to the graph below:
The maximum timeout period given in the graph is 1500 seconds. If a timeout period of more than 1500 seconds is required, please use the following equation:
where CSWT is in pF and tWD is microseconds.
Please note that a capacitor with low leakage current and low temperature coefficient should be used (e.g X7R ceramic capacitor)
