Detailed Description：

CN705/706/707/708/813 series is a microprocessor supervisory circuit that monitors the power supply to

digital circuits such as microprocessor, controller and memory . These devices assert reset during power up,

power down or brownout condition to prevent code execution errors.

RESET output

On power up, once VCC reaches 1.15V, CN705/706/707/708/813 series output a reset signal . As VCC

increases, the reset signal stays valid; When VCC rises above reset threshold, an internal timer releases

RESET (

) after 200ms. RESET (

) becomes valid once VCC dips below reset threshold

during power down or in brownout condition. If brownout occurs in the middle of a previously initiated
