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)。

stm809 / stm810 / stm811 / stm812 特點

• stm809(低電平)/stm810(高電平)復位邏輯輸出，兼容imp809/810
• 具有更低的2.6ua～6ua電流消耗，更適用于電池供電的電源系統
• 具有外部手動復位功能的stm811/812供選擇
• sot23(stm809/810)和sot143(stm811/812)兩種封裝
• precision monitoring of 3v, 3.3v, and 5v supply voltages
• two output configurations
  – push-pull rst output (stm809/811)
  – push-pull rst output (stm810/812)
• 140ms reset pulse width (min)
• low supply current - 6μa (typ)
• guaranteed rst/rst assertion
  down to vcc = 1.0v
• operating temperature:
  –40°c to 85°c (industrial grade)
• lead-free, small sot23 and sot143 package

stm809 / stm810 / stm811 / stm812 特性
