TPS3840DL31DBVR TI Voltage Supervisor | SOT-23-5 | 3.1V Threshold, Active Low

Product Overview

The TPS3840DL31DBVR from Texas Instruments is a high-performance voltage supervisor designed for reliable system monitoring. Housed in a compact SOT-23-5 package, this device monitors supply voltages and asserts a reset signal when the voltage falls below a preset threshold. With a fixed threshold of 3.1V and an active-low, open-drain output, it ensures robust protection for microcontrollers, DSPs, and other sensitive circuits. The TPS3840 series offers ultra-low quiescent current (typically 220 nA), making it ideal for battery-powered and energy-efficient applications.
