TPS3840DL42DBVRQ1 TI Voltage Supervisor | SOT-23-5 | 4.2V Threshold, 1.5% Accuracy

Product Overview

The TPS3840DL42DBVRQ1 is a high-accuracy voltage supervisor from Texas Instruments, designed for automotive and industrial applications. It monitors supply voltages and asserts a reset signal when the voltage drops below a preset threshold. Housed in a compact SOT-23-5 package, it offers a fixed threshold of 4.2V with ±1.5% accuracy over temperature. The device features a low quiescent current of 2.5 µA typical, making it suitable for battery-powered systems. It is AEC-Q100 qualified for automotive applications.
