General Description：

CN825 series is a family of microprocessor (uP) supervisory circuit that monitors microprocessor’s supply voltage and battery voltage. The CN825 series integrates uP reset circuit with 200ms delay, Watchdog, manual reset circuit. These devices reduce system complexity, hence improve system reliability.

CN825 series generates a reset signal when VCC is lower than reset threshold. The reset threshold is internally fixed with 1% accuracy. The watchdog timer’s timeout period is internally set at typical value of 1.6s. CN825 series provide both active low and active high reset signals.

CN825 series is ideal for applications in automotive systems, computers, controllers and intelligent instruments.

All devices are available in 6 pin SOT-23 package.
