The TPS2066CDQNR is a state-of-the-art power distribution switch from Texas Instruments, designed for applications where multiple USB ports require power management. This integrated circuit is part of the TPS2066 family, known for its single-channel, current-limited, power-distribution switches optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Current Limiting: The device provides 1.5A of continuous current with an accurate current-limiting response to protect the host device and USB peripherals from overcurrent conditions.
• Thermal Shutdown: It includes a thermal shutdown feature that prevents damage from overheating. If the die temperature rises above a preset threshold, the thermal protection circuitry shuts off the switch to prevent damage.
• Reverse Voltage Protection: The TPS2066CDQNR prevents damage to the system if the input voltage is accidentally reversed, enhancing system reliability.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates at the correct voltage level, which is critical for stable and reliable system performance.

Applications

With its robust design, the TPS2066CDQNR is suitable for a wide range of applications, including but not limited to:

• USB hubs and peripherals
• Desktop and notebook computers
• Consumer electronics
• Portable equipment

Technical Specifications

The device comes in a compact QFN package and operates over a wide range of input voltages. It is designed to handle normal USB operating conditions and is compliant with USB 2.0 standards. The TPS2066CDQNR also features a fast overcurrent response time, which is critical for protecting sensitive electronic devices connected to the USB ports.

Quality and Reliability

As with all Texas Instruments products, the TPS2066CDQNR is manufactured to the highest quality standards, ensuring reliable performance in even the most demanding applications. The device is RoHS compliant and is designed to meet the requirements of modern electronic equipment.
