TLC7703IDR TI Supervisor IC | 8-SOIC | 2.7V-6V, Active-Low Reset

Product Overview

The TLC7703IDR from Texas Instruments is a supply voltage supervisor IC designed for monitoring power supply rails in digital systems. It provides a precision voltage reference and a comparator to monitor the supply voltage (VDD) and assert a reset signal when the voltage falls below a preset threshold. The device features an active-low, open-drain reset output (RESET) that remains asserted for a fixed timeout period after the supply voltage rises above the threshold. The TLC7703IDR operates over a wide supply voltage range of 2.7V to 6V and is available in the industry-standard 8-SOIC package. It is ideal for applications requiring reliable power-on reset and brown-out protection in microcontrollers, DSPs, and other logic systems.

產品概述

TLC7703IDR 是德州儀器（TI）推出的一款電源電壓監控IC，專為監控數位系統中的電源軌而設計。它包含一個精密電壓參考和一個比較器，用於監控電源電壓（VDD），並在電壓低於預設閾值時發出重置信號。該器件具有低電平有效、開漏輸出的重置信號（RESET），在電源電壓上升到閾值以上後，重置信號會保持一段固定的超時時間。TLC7703IDR 的工作電源電壓範圍為 2.7V 至 6V，採用業界標準的 8-SOIC 封裝。它非常適合需要可靠上電復位和欠壓保護的應用，如微控制器、DSP 和其他邏輯系統。
