R8356 Series
Watchdog Timer Equipped with Inhibit Pin with VD
The R8356 Series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip. R8356 monitors the power system of devices equipped with microprocessors and prevents system runaway with a reset signal when a malfunction occurs. The output delay time of the VD and watchdog timeout period/reset time can be adjusted high accuracy by an external capacitor. The R8356 is equipped with the function that inhibits clock monitoring of the WDT (INH).
