STM809 / STM810 / STM811 / STM812 復位電路

STM809 / STM810 / STM811 / STM812 概述

STM809 / STM810 / STM811 / STM812 是專用于產生微處理器復位功能的芯片。STM809 / STM810 / STM811 / STM812 在電源上電、掉電以及監控系統電源電壓的變化，產生可靠的電源復位信號，使微控制器產生復位或處理中斷事件。典型工作電流為6μA/5V,2.6μA/3.3V的STM809 / STM810 / STM811 / STM812 與同類型器件相比,更適合電池供電的儀器、設備。

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)。
