Overview

Product Highlight


National Semiconductor creates analog-intensive solutions that differentiate customers’ products by providing greater energy efficiency, precision, portability, better audio and sharper images in electronic systems. Analog technologies, also known as linear technologies, are the essential link between the digital world of ones and zeroes and the real world of light, sound, temperature, speed, and pressure. National’s technologies address issues facing system designers in markets such as mobile handsets, communications and industrial applications.

National’s analog portfolio features leading-edge operational amplifiers, interface technologies, data converters, and power management solutions. These devices provide solutions for high-efficiency lighting, precision data acquisition, high-speed serial communication and power conversion. As a recognized world leader in power management, National continues to pioneer new energy-efficient devices, sub-systems and architectures for next-generation system designs. 

A Universal Serial Bus (USB) switch allows two or more computers to easily share USB peripherals like printers, cameras and scanners. The USB switch eliminates the need to unplug the USB peripheral component from one computer, to plug it into the other. Instead, the shared component runs to the USB switch device itself, which is connected in turn to multiple computers. With the touch of a button on the USB switch device, the peripheral is instantly available to serve any computer connected to it.

There are several models of USB switches. Some models are built for two computers to share a single device. This can be handy for a home user who needs to share a USB-enabled printer, scanner, memory card reader or digital camera, for example, between a desktop and laptop. Other models allow incoming ports or connectors for up to four computers, and an outgoing USB port for one device. Still others allow up to four computers to share up to four USB-enabled devices.

The LM3526 provides Universal Serial Bus standard power switch and over-current protection for all host port applications. The dual port device is ideal for Notebook and desktop PC's that supply power to more than one port.

A 1 ms delay on the fault flag output prevents erroneous overcurrent reporting caused by in-rush currents during hot-plug events.

The dual stage thermal protection circuit in the LM3526 provides individual protection to each switch and the entire device. In a short-circuit/over-current event, the switch dissipating excessive heat is turned off, allowing the second switch to continue to function uninterrupted.

The LM3526 accepts an input voltage between 2.7V and 5.5V allowing use as a device-based in-rush current limiter for 3.3V USB peripherals, as well as Root and Self-Powered Hubs at 5.5V. The Enable inputs accept both 3.3V and 5.0V logic thresholds.

The small size, low RON, and 1 ms fault flag delay make the LM3526 a good choice for root hubs as well as per-port power control in embedded and stand-alone hubs.

LM3526MX-L/NOPB is a 8 pin SOIC narrow, dual port USB Power switch and over-current protection. It has a 2.7V to 5.5V input voltage range and includes a 500mA minimum continous load current. It is compatible with USB1.1 and USB 2.0.
