The TPS3305-33D is a highly reliable, dual voltage supervisor (SVS) integrated circuit designed and manufactured by Texas Instruments (TI). This device is particularly tailored for applications requiring precision voltage monitoring to ensure proper system functionality and stability.

Key Features

• Voltage Supervision: The TPS3305-33D supervises 3.3V supply voltages, with a fixed-sense threshold voltage for the primary channel at 3.3V and an adjustable threshold for the secondary channel.
• Dual SVS: It features two independent voltage supervisors, making it suitable for systems with multiple supply voltages that need simultaneous monitoring.
• Low Supply Current: The device is designed for low-power operation, drawing a quiescent current of typically 40 µA, which is ideal for battery-powered and portable applications.
• Manual Reset Input: It includes a manual reset input that allows for an external trigger to initiate a system reset, providing additional flexibility and control.
• Reset Time Delay: The TPS3305-33D offers an internally fixed delay time for the reset output, ensuring sufficient time for the system to stabilize after a voltage fault before resuming operation.

Applications

The TPS3305-33D is suitable for a wide range of applications that require reliable and accurate voltage monitoring. Common applications include:

• DSP and Processor-Based Systems
• Industrial Equipment
• Portable/Battery-Powered Devices
• Networking Equipment
• Telecommunication Systems

Quality and Reliability

As with all Texas Instruments products, the TPS3305-33D is designed to meet the highest standards of quality and reliability. It is available in an 8-pin Small Outline Integrated Circuit (SOIC) package, making it easy to integrate into various circuit designs. The device also features built-in over-temperature protection, ensuring it operates within safe temperature ranges for enhanced durability and performance longevity.
