XC6124 Series

Voltage Detector with Watchdog Function and ON/OFF Control

The XC6124 series are highly accurate, low power consumption CMOS voltage detectors with a watchdog function and ON/OFF control.

As the watchdog timeout period & release delay period is internally set the time can be fixed and it is possible to have a system monitor without the need for external components. By making use of the newly added EN/ENB pin the watchdog function can be turned OFF allowing the series to be used as a simple voltage detector. With the XC6124 series, since the EN/ENB pin is internally pulled up to VIN or pulled down to VSS, it is possible to use the watchdog function even when the pin is OPEN. Detect voltage is fixed within a range of 1.6V~5.0V, selectable in 0.1V increments.

QuestionWhat does the watchdog timer work?
Answer

This timer function is continuously monitoring to check whether the microcomputer is normally operating or not and give notice of any abnormal operation.
