TPS3840PL31DBVR TI Voltage Supervisor | SOT-23-5 | 3.1V Threshold, Active Low

Product Overview

The TPS3840PL31DBVR is a high-performance voltage supervisor from Texas Instruments, designed for precise power monitoring in a compact SOT-23-5 package. It features a fixed threshold voltage of 3.1V with a typical accuracy of ±1.5% over temperature, ensuring reliable system reset during power-up, power-down, and brown-out conditions. The device consumes ultra-low quiescent current of 350 nA (typical), making it ideal for battery-powered and energy-efficient applications. It offers an active-low, open-drain RESET output with a built-in pull-up resistor, eliminating the need for external components. The TPS3840PL31DBVR operates over a wide supply voltage range of 1.5V to 6.0V and is specified for the industrial temperature range of -40°C to +125°C.
