... R5106N SERIES OUTLINE The R5106N Series are CMOS-based µ con supervisory circuit, or high accuracy and ultra low supply current voltage detector with built-in delay and watchdog timer. When the supply voltage is down across the threshold, or the watchdog timer does not detect the system clock from the voltage detector circuit is used for the system reset, etc ...

... R5106N OPERATION M When the power supply, V released delay time (or the power on reset time tpLH), the output of RESETB becomes “H” level. N When the SCK pulse is input, the watchdog timer is cleared, and CT pin mode changes from discharge mode to charge mode. When the CT pin voltage becomes higher than VREFH, the mode will change into discharge, and next watchdog time count starts ...
