TPS3840PL42DBVR TI Voltage Supervisor | SOT-23-5 | 4.2V Threshold, 1% Accuracy

Product Overview

The TPS3840PL42DBVR from Texas Instruments is a high-accuracy voltage supervisor (reset IC) designed for monitoring power supply voltages in a wide range of applications. Housed in a compact SOT-23-5 package, this device offers a fixed threshold voltage of 4.2V with ±1% 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 brown-out conditions. The TPS3840PL42DBVR operates over a supply voltage range of 1.5V to 6.0V and consumes ultra-low quiescent current of typically 350 nA, making it ideal for battery-powered and energy-efficient systems.
