For Consumer / IoT
The R5109 Series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip.
R5109 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. R5109 is equipped with the function that inhibits clock monitoring of the WDT (INH) and the function to supervise two different clocks.
