TPS3103K33DBVR TI Voltage Supervisor | SOT-23-6 | 3.3V Threshold, Active-Low Reset

Product Overview

The TPS3103K33DBVR from Texas Instruments is a low-power, voltage supervisor (reset IC) designed for monitoring 3.3V supply rails. It features a precision voltage reference and a comparator that asserts a reset signal when VDD falls below the threshold voltage (2.93V typical). The reset output remains active for a fixed timeout period after VDD rises above the threshold. Housed in a compact SOT-23-6 package, it is ideal for space-constrained applications requiring reliable power-on reset and brown-out protection.

Detailed Technical Specifications

Key Features

• Precision voltage monitoring with 2% threshold accuracy
• Ultra-low supply current of 2.2µA
• Fixed reset timeout period (200ms) eliminates external components
• Open-drain RESET output allows wired-OR connection
• Guaranteed RESET valid down to VDD = 0.9V
• Small SOT-23-6 package saves board space

Target Applications

• 5G base station power management
• Automotive dashboard and infotainment systems
• Industrial PLC and motor control
• Portable medical devices (e.g., glucose meters)
• IoT edge nodes and smart sensors

產品概述

TPS3103K33DBVR 是德州儀器 (TI) 推出的一款低功耗電壓監控器 (復位 IC)，專為監控 3.3V 電源軌而設計。它內置精密電壓基準和比較器，當 VDD 降至閾值電壓 (典型值 2.93V) 以下時，會觸發復位信號。復位輸出在 VDD 回升至閾值以上後，保持有效一段固定的超時時間。採用緊湊的 SOT-23-6 封裝，非常適合需要可靠上電復位和掉電保護的空間受限應用。
