LP3470A400DBVR TI Voltage Supervisor | SOT-23-5 | 4.0V Threshold, Active-Low Reset

Product Overview

The LP3470A400DBVR from Texas Instruments is a low-power voltage supervisor designed for monitoring power supply voltages in microprocessor and digital systems. It provides a precision voltage threshold of 4.0V and asserts a reset signal when the monitored voltage falls below this threshold. The device features an active-low, open-drain reset output that remains asserted for a fixed timeout period after the voltage rises above the threshold. Housed in a compact SOT-23-5 package, it is ideal for space-constrained applications requiring reliable power-on reset and brown-out protection.

產品概述

LP3470A400DBVR 是德州儀器 (TI) 推出的一款低功耗電壓監控器，專為監控微處理器和數位系統的電源電壓而設計。它提供精確的 4.0V 電壓閾值，當監控電壓低於此閾值時會觸發重置信號。該器件具有低電平有效、開漏輸出的重置信號，在電壓回升至閾值以上後，重置信號會保持一段固定的超時時間。採用緊湊的 SOT-23-5 封裝，非常適合需要可靠上電重置和掉電保護的空間受限應用。
