Introducing the LM3526MX-H Dual Port USB Power Switch from Texas Instruments

The LM3526MX-H is a highly integrated solution designed by Texas Instruments to manage and protect power delivery via USB ports. This advanced power switch is specifically tailored for dual-port applications, making it an ideal component for devices with multiple USB interfaces such as desktop and laptop computers, docking stations, and monitors that serve as USB hubs.

Key Features:

• Dual USB Port Power Control: The LM3526MX-H can independently control the power to two USB ports, allowing for selective enablement and overcurrent protection for each port.
• Overcurrent Protection: This device ensures the safety of electronic equipment by providing overcurrent protection. It prevents damage to USB ports by limiting the current that can be drawn by connected devices.
• Thermal Shutdown: The built-in thermal shutdown feature adds an additional layer of protection, preventing overheating and potential damage to both the power switch and the connected devices.
• High-Side MOSFET: The integrated high-side MOSFET allows for low on-resistance, which translates to lower power dissipation and improved efficiency.
• Fault Reporting: In the event of an overcurrent condition or thermal shutdown, the LM3526MX-H provides a fault report through an open-drain output, enabling the system to take corrective action.

The LM3526MX-H comes in a compact SOP-16 package, which is space-saving and suitable for high-density PCB layouts. This power switch operates over a wide voltage range, accommodating the various power requirements of USB peripherals. Its low quiescent current ensures minimal power consumption when in standby mode, making it an energy-efficient choice for modern electronics.

With its robust feature set and Texas Instruments' reputation for quality and reliability, the LM3526MX-H is a top choice for designers looking to incorporate safe and efficient USB power delivery into their products. Whether for personal computing accessories or industrial applications, the LM3526MX-H delivers the performance and protection needed for a seamless user experience.
