XC6130/XC6131 Series
Watchdog Timeout Period Externally Adjustable Voltage Detector
ETR02026-005
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 LH 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 VIN, and thus these pins can be left open when not used.
