TPS3840PL28DBVRQ1 TI Supervisory Circuit | SOT-23-5 | 2.8V Threshold, Active-Low Reset

Product Overview

The TPS3840PL28DBVRQ1 from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for automotive and industrial applications. It monitors supply voltages and asserts a reset signal when the voltage falls below a preset threshold of 2.8V. Housed in a compact SOT-23-5 package, this device offers a precision voltage reference and a built-in delay timer to ensure reliable system reset. With a quiescent current of typically 1.5 µA, it is ideal for battery-powered and energy-efficient systems. The TPS3840PL28DBVRQ1 is AEC-Q100 qualified for automotive applications, ensuring robust performance in harsh environments.
