TPS3779ADBVT TI Supervisory Circuit | SOT-23-6 | 0.5% Accuracy, 1.8V Threshold

Product Overview

The TPS3779ADBVT from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for monitoring voltage levels in a wide range of applications. Housed in a compact SOT-23-6 package, this device offers a precision voltage threshold of 1.8V with ±0.5% accuracy over temperature. It features an open-drain active-low reset output with a built-in pull-up resistor, ensuring reliable system reset during power-up, power-down, and brownout conditions. The TPS3779ADBVT operates over a supply voltage range of 1.6V to 6.5V, making it suitable for both 1.8V and 3.3V systems. Its ultra-low quiescent current of 1.5µA (typical) extends battery life in portable applications.
