TL7733BCDR TI Voltage Supervisor | 8-SOIC | 3.3V Threshold, Active-Low Reset

Product Overview

The TL7733BCDR from Texas Instruments is a precision voltage supervisor designed for monitoring 3.3V power supplies. It provides a reset signal to microprocessors, microcontrollers, and other digital systems during power-up, power-down, and brown-out conditions. The device features a fixed threshold voltage of 3.3V with a typical accuracy of ±2%. 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 an 8-SOIC package, the TL7733BCDR is ideal for space-constrained applications requiring reliable voltage monitoring.
