XD6131 Series

Watchdog Timeout Period Externally Adjustable Voltage Detector

*AEC-Q100 (Grade1) compliant

The XD6131 series are voltage detectors with a watchdog function. The watchdog timeout time and release delay time can be set as desired using a single external capacitor. These voltage detectors are used for microprocessor monitoring, and when the power voltage reaches the detect voltage or an L→H pulse is not input to the watchdog pin within the watchdog timeout time, an L level signal is output from the RESETB pin.

The XD6131 series has a manual reset function. When the manual reset pin is set to Low level at any desired timing, an L level signal is output from the RESETB pin.

*TOREX’s automotive products (XD Series) are AEC-Q100 compliant.
