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 with 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

Temp. coeff. of Detector Threshold ···Typ. ± 100ppm/°C

)

···1.5V to 5.5V (internally fixed)

• Reset Hold Time of WDT(tWR)·········Typ. 34ms (CTW=0.1μF)

•

Watchdog Timeout Period Accuracy ····± 33% (-40°C Topt 105°C)

• Package··········································SSOP-8G
