TPS3831A09DQNT TI Supervisory Circuits | 4-X2SON (1x1) | 2.5V Threshold, Active-Low Reset

Product Overview

The TPS3831A09DQNT from Texas Instruments is a low-power, voltage supervisory circuit designed for monitoring power supplies in portable and battery-powered applications. It features a precision voltage reference and a comparator that monitors the supply voltage (VDD) and asserts a reset signal when VDD falls below the factory-programmed threshold of 2.5V. The device operates over a wide supply voltage range of 1.5V to 6.0V and consumes only 220 nA (typical) of quiescent current, making it ideal for energy-sensitive designs. The reset output is active-low and remains asserted for a minimum of 200 ms after VDD rises above the threshold, ensuring proper system initialization. Housed in a compact 4-pin X2SON (1x1 mm) package, the TPS3831A09DQNT is suitable for space-constrained applications.

產品概述

TPS3831A09DQNT 是德州儀器（TI）推出的一款低功耗電壓監控電路，專為監測可攜式和電池供電設備的電源而設計。它包含一個精密電壓參考和一個比較器，用於監測供電電壓（VDD），並在 VDD 低於工廠編程的 2.5V 閾值時觸發復位信號。該器件的工作電壓範圍為 1.5V 至 6.0V，典型靜態電流僅 220 nA，非常適合節能設計。復位輸出為低電平有效，並在 VDD 回升至閾值以上後保持至少 200 ms，確保系統正常初始化。採用緊湊的 4 引腳 X2SON（1x1 mm）封裝，適用於空間受限的應用。
