TLV803EA38DPWR TI Supervisory Circuit | 5-X2SON (0.8x0.8) | 3.8V Threshold, Active-Low Reset

Product Overview

The TLV803EA38DPWR from Texas Instruments is a supervisory circuit (reset IC) designed to monitor power supply voltages in digital systems. It provides a reset signal to the host processor or logic when the supply voltage drops below a preset threshold, ensuring reliable system operation during power-up, power-down, and brownout conditions. Housed in a compact 5-X2SON (0.8x0.8) package, it is ideal for space-constrained applications. The device features a fixed threshold voltage of 3.8V, active-low open-drain reset output, and a built-in delay time of 200ms (typical) to prevent false resets during power transients.
