TPS3307-33DR TI Supervisory Circuits | 8-SOIC | 3.3V, 2.93V Threshold

Product Overview

The TPS3307-33DR from Texas Instruments is a supervisory circuit designed for monitoring multiple supply voltages. It features a precision voltage reference and a comparator that monitors the 3.3V supply and a second adjustable input. The device asserts a reset signal whenever the monitored voltage falls below its threshold, ensuring proper system initialization and operation. Housed in an 8-pin SOIC package, it is ideal for applications requiring reliable power-up and power-down sequencing.
