R5101中文资料带看门狗定时器的系统电源数据手册Nisshinbo规格书

描述 Description

The R5101 Series are CMOS-based system power ICs with a voltage regulator (VR) featuring 50mA output, a voltage detector (VD) and a watchdog timer (WDT) integrated in a single chip. R5101 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 R5101 is equipped with the function that inhibits clock monitoring of the WDT (CE).
