XC6130/XC6131 Series

Watchdog Timeout Period Externally Adjustable Voltage Detector

ETR02026-007

■ GENERAL DESCRIPTION

The XC6130/XC6131 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 XC6130 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.

The XC6131 series has a watchdog ON/OFF function. By setting the EN pin to L level, the watchdog function can be turned

OFF while the voltage detector that monitors the power voltage continues to operate.

The MRB pin and EN pin are pulled up internally to V_IN, and thus these pins can be left open when not used.
