R5107 系列
看门狗定时器，配置手动复位，带VD功能
概述
The R5107 Series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip. R5107 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 R5107 is equipped with the function that inhibits clock monitoring of the WDT (INH) and manual reset (MR) that also stops the VD.
