TPS3839G18DBZT TI Voltage Supervisor | SOT-23-3 | 1.8V Threshold, Active-Low Reset

Product Overview

The TPS3839G18DBZT from Texas Instruments is a precision voltage supervisor designed for monitoring supply voltages in digital systems. It features a fixed threshold voltage of 1.8V with a 2.5% accuracy over temperature. The device asserts a reset signal when VDD falls below the threshold and maintains it for a minimum of 200ms after VDD rises above the threshold. Housed in a compact SOT-23-3 package, it is ideal for space-constrained applications requiring reliable power-on reset and brown-out protection.
