TPS3837E18QDBVRQ1 TI Supervisory Circuit | SOT-23-5 | 1.8V Threshold, Active-Low Reset

Product Overview

The TPS3837E18QDBVRQ1 from Texas Instruments is a supervisory circuit designed for monitoring power supplies in automotive and industrial applications. It provides a precision voltage monitor with a fixed threshold of 1.8V, ensuring reliable system reset during power-up, power-down, and brown-out conditions. Housed in a compact SOT-23-5 package, this device offers a low-power solution with a typical supply current of 220 nA. The active-low reset output remains asserted for a minimum of 200 ms after VDD rises above the threshold, providing a stable reset signal for microcontrollers and other digital systems.
