TPS3307-33DGN TI Supervisory Circuit | 8-HVSSOP | 3.3V, Dual Supply Monitor

Product Overview

The TPS3307-33DGN is a supervisory circuit from Texas Instruments designed for monitoring dual supply voltages in microprocessor and digital systems. It operates with a 3.3V monitored supply and a secondary supply (e.g., 1.8V, 2.5V, or adjustable). The device asserts a reset signal when either supply falls below its threshold, ensuring reliable system operation during power-up, power-down, and brownout conditions. Housed in an 8-pin HVSSOP package, it offers a compact solution for space-constrained applications.

Detailed Technical Specifications

Key Features

• Dual supply monitoring with fixed 3.3V and adjustable second threshold
• Precision voltage reference with ±2% accuracy over temperature
• 200ms reset delay prevents false triggering during transients
• Low supply current of 15µA (typical)
• Open-drain RESET output for wired-OR connection
