TPS3840PL48DBVR TI Voltage Supervisor | SOT-23-5 | 4.8V Threshold, Active Low

Product Overview

The TPS3840PL48DBVR 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 4.8V with a typical accuracy of ±1%, 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. With an active-low open-drain output, it integrates seamlessly with microcontrollers and other digital logic.
