CN705/706/707/708/813
Description
CN705/706/707/708/813 series is a family of microprocessor (uP) supervisory circuit that monitors microprocessor’s supply voltage and battery voltage. CN705/706/707/708/813 series integrates uP reset circuit with 200ms delay, Watchdog, manual reset circuit and a power fail comparator with 1.22V threshold. These devices reduce system complexity, hence improve system reliability. CN705/706/707/708/813 series has several functional options. Each device generates a reset signal when VCC is lower than reset threshold. In addition, CN705, CN706 and CN813 have a watchdog timer whose timeout period is 1.6s.
