Reset threshold：4.4V Low
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. CN707 and CN708 provide both active low and active high reset signals, but have no watchdog function. CN813 are same as CN705/706 except active high reset is provided instead of active low.
CN705/706/707/708/813 series is ideal for applications in automotive systems, computers, controllers and intelligent instruments. All devices are available in 8 pin SOP package.
