STM809 / STM810 / STM811 / STM812 复位电路

STM809 / STM810 / STM811 / STM812 概述

STM809 / STM810 / STM811 / STM812 是专用于产生微处理器复位功能的芯片。STM809 / STM810 / STM811 / STM812 在电源上电、掉电以及监控系统电源电压的变化，产生可靠的电源复位信号，使微控制器产生复位或处理中断事件。典型工作电流为6μA/5V,2.6μA/3.3V的STM809 / STM810 / STM811 / STM812 与同类型器件相比,更适合电池供电的仪器、设备。

The STM809 / STM810 / STM811 / STM812 MICROPROCESSOR RESET Circuits are low-power supervisory devices used to monitor power supplies. They perform a single function: asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time (trec). The STM811/812 also provide a push-button reset input (MR)。
