Reset IC
Product Description
GSR809
Reset IC
Product Description
The GSR809 is microprocessor (μP) supervisory circuit used to monitor the power supplies in μP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or 2.5V powered circuits.
The circuit perform a single function: it asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.
The GSR809 has push-pull output and has an active-low output. The reset comparator is designed to ignore fast transients on VCC, and the output is guaranteed to be in the correct logic state for VCC down to 1.15V within the range of the operating temperature .

重置IC
產品描述
GSR809 是一款微處理器（μP）監控電路，用於監控μP和數位系統中的電源。當與+5V、+3.3V、+3.0V或2.5V供電的電路一起使用時，它通過消除外部元件和調整來提供卓越的電路可靠性和低成本。
該電路執行單一功能：當VCC供電電壓低於預設閾值時，它會發出重置信號，並在VCC回升至重置閾值後至少保持140ms。提供適用於各種供電電壓的重置閾值選項。
GSR809具有推挽輸出並具有有效低輸出。重置比較器設計用來忽略VCC上的快速瞬變，並且保證輸出在VCC最低至1.15V範圍內始終處於正確的邏輯狀態。
