ADI medical industrial USB isolation scenario costs by 25%

Analog Devices, Inc., the global high performance signal processing solution suppliers, the newly launched the industry's first single-chip USB isolator (universal serial bus isolator), the device can simplify medical and industrial equipment of isolated USB port implementation.

USB port provides an implementation of peripherals and the connection between your computer and disconnect the simple standardized method, you do not need to restart or shutdown the system.

ADuM4160 as the industry's first single-package USB isolator is a truly integrated chip replaces complex Board-level solutions, not only can help engineers by simplifying design improve time to market, but also meet the harsh environment applications on USB application needs in size and costs have been reduced at the same time, power and cooling performance is very much improved, can meet the most stringent requirements of the medical and industrial standards.

Now, with the PC architecture more and more markets favor, USB has also become PC interface for the common criteria.

If you must isolate a PC connected devices, people naturally will select the USB interface. USB a wide range of industrial and medical support and simple structure so that it becomes a common PC interfaces, serial ports are gradually being phased out. In the meantime, two USB with the name of the application isolation is based on PC platform of medical equipment and has a very significant difference of industrial applications.

When you need information, USB-compatible medical devices so that doctors can at any time in various locations, easily and efficiently share the file or critically ill patients.

Supported USB device so that the health care staff can use the extensive variety of cost-effective peripherals. For the health of millions of people around the world to maintain, for patient care, disease management, sanitation and health, as well as drug distribution device is indispensable, therefore to support USB health care equipment demand is growing.

ADuM4160 USB isolator with ADI's iCoupler ® isolation technology, digital can provide valid values for the medical grade 5kV isolation, upstream short-circuit protection and full isolation of 1.5Mbps and 12Mbps data rate (IEC 60601-1 medical security authentication is processed).

This device complies with the USB standard, beyond 2.0 is lower than the current data isolation scenario of cost and complexity of achieving a fully isolated USB functionality, thus enabling medical and industrial design engineers to reduce up to 25% of the cost, the design size decreases by half, and the development time from months to weeks.

"ADI's new USB isolator for design engineers provides a pioneering new program that acts as an alternative to expensive and time-consuming traditional USB isolation scenario.

Legacy USB quarantine programmes need a transceiver is a bidirectional USB differential signal is converted to a more compatible with the traditional discrete signal isolator, this transceiver is costly and takes up a larger space, "analog isolation products division product line Director said," the Ronn Kliger ADuM4160 in a compact IC in all USB signal processing and isolation. ”

Based on the analog devices, Inc. iCoupler technology (integrated high-speed complementary metal oxide semiconductor (CMOS) and chip-level, micro transformer technology), ADuM4160 easily at low and full speed USB system implementation.

It uses externally supplied 5V USB power supply, or by the system using internal regulator for 3 .3V power supply. ADuM4160 also provides a pull-up resistor of quarantine control, so that peripheral is able to control the connection time. It is in the idle state of the current low-2mA (maximum values), without the suspended state

"Medical design generally use isolated RS-232 or Ethernet connection, the connection limit for the data transfer rate, does not support Plug and play functionality and taking too much space," ADI healthcare Director Patrick Doherty said, O ' "ADuM4160 USB isolator, enhanced medical isolation level allows engineers to design helps to better facilitate the care of patients ' medical device USB.
