Voltage Detector with Watchdog Function and ON/OFF Control

The XC6123 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.

Detect voltage is fixed within a range of 1.6V~5.0V, selectable in 0.1V increments.
