The R5105N series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip. R5105N 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 R5105N Series are CMOS-based system power ICs that integrate a voltage detector (VD) and a watchdog timer (WDT). These devices monitor the power supply of systems equipped with microprocessors to prevent runaway conditions by issuing a reset signal when malfunctions occur. The output delay time for the VD and the watchdog timeout period can be accurately adjusted using external capacitors.
