R5107G Series  
Watchdog Timer Equipped with Manual Reset with VD  
The R5107G Series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip.  
R5107G 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 by an external capacitor with  
a high degree of accuracy. The R5107G is equipped with the function that inhibits clock monitoring of the WDT (INH) and manual reset (MR)  
that also stops the VD.  
FEATURES

• Output Delay Time Accuracy··········± 16% (-40°C ≤ Topt ≤ 105°C)  
(WDT Section)  
• Watchdog Timeout Period(tWD)·······Typ. 310ms (CTW=0.1μF)  
• Reset Hold Time of WDT(tWR)·········Typ. 34ms (CTW=0.1μF)
