TLV809EC46DBZR TI Supervisor IC | SOT-23-3 | 4.63V Threshold, Active-Low Reset

Product Overview

The TLV809EC46DBZR is a supervisory circuit from Texas Instruments designed to monitor power supplies in digital systems. It provides a reset output to the microprocessor during power-up, power-down, and brown-out conditions. The device operates over a wide supply voltage range and features a fixed threshold voltage of 4.63V. The reset output is active-low and remains asserted for a minimum of 140ms after the supply voltage exceeds the threshold, ensuring proper system initialization. Housed in a compact SOT-23-3 package, it is ideal for space-constrained applications.
