Low Power Microprocessor Supervisory Circuits

CN705/706/707/708/813

Description：

Features：

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.

Reset threshold can be from 2.6V to

5.0V with 0.1V step.

CN705/706/707/708/813 series has several

functional options. Each device

generates

Pin-to-pin compatible with industry

standard 705/706/707/708/813

Available in DIP8 and SOP8

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.
