TPS3808EG25DBVR TI Supervisory Circuit | SOT-23-6 | 2.5V Threshold, Active-Low Reset

Product Overview

The TPS3808EG25DBVR is a supervisory circuit from Texas Instruments (TI) designed to monitor power supply voltages in digital systems. It provides a reset signal to the host processor or system logic when the monitored voltage falls below a preset threshold, ensuring reliable system operation during power-up, power-down, and brown-out conditions. This device features a fixed threshold voltage of 2.5V, an active-low open-drain reset output, and a manual reset input. Housed in a compact SOT-23-6 package, it is ideal for space-constrained applications requiring high accuracy and low power consumption.
