TPS3103H20DBVR TI Voltage Supervisor | SOT-23-6 | 2.0V Threshold, Active-Low Reset

Product Overview

The TPS3103H20DBVR from Texas Instruments is a low-power, voltage supervisory circuit designed for monitoring power supply voltages in digital systems. It provides a precision voltage reference and a comparator that monitors the VDD input for undervoltage conditions. When the monitored voltage falls below the factory-programmed threshold (2.0V typical), the RESET output asserts low. The device features a fixed delay time of 200ms (typical) to ensure stable system reset. Housed in a compact SOT-23-6 package, it is ideal for space-constrained applications requiring reliable voltage monitoring.
