R8359 系列

看门狗定时器，配置双时钟监控，带VD功能

概述

The R8359 Series are CMOS-based system power ICs with a voltage detector (VD) and watchdog timer (WDT) integrated in a single chip.

R8359 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. R8359 is equipped with the function that inhibits clock monitoring of the WDT (INH) and the function to supervise two different clocks.
