TPS3305-33DR TI Supervisory Circuits | 8-SOIC | 3.3V, Dual Processor Monitor

Product Overview

The TPS3305-33DR from Texas Instruments is a dual processor supervisor circuit designed for monitoring two independent supply voltages in digital systems. It provides reset signals to microprocessors, DSPs, or other logic circuits during power-up, power-down, and brown-out conditions. The device operates with a 3.3V supply and features a precision voltage reference and a programmable reset delay. Housed in an 8-pin SOIC package, it is ideal for space-constrained applications requiring reliable system supervision.
