STM819LM6F ST Supervisory Circuit | 8-SOIC | 2.63V Threshold, Active Low Reset

Product Overview

The STM819LM6F is a supervisory circuit from STMicroelectronics designed to monitor power supply voltages in microprocessor systems. It provides a reset output during power-up, power-down, and brownout conditions. The device features a precision voltage reference and comparator that monitors the VCC input for undervoltage conditions. When VCC falls below the reset threshold (2.63V typical), the RST output goes low and remains low for a minimum reset timeout period after VCC rises above the threshold. The STM819LM6F is available in an 8-pin SOIC package and is ideal for applications requiring reliable system reset functionality.

產品概述

STM819LM6F是意法半導體推出的監控電路，專為微處理器系統的電源電壓監控而設計。該器件在電源上電、掉電和電壓跌落情況下提供復位輸出。它包含一個精密電壓基準和比較器，用於監控VCC輸入的欠壓情況。當VCC降至復位閾值（典型值2.63V）以下時，RST輸出變為低電平，並在VCC升至閾值以上後保持低電平至少一個復位超時週期。STM819LM6F採用8引腳SOIC封裝，適用於需要可靠系統復位功能的應用。
