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)。
