NVE Introduces Isolated CAN Transceiver
NVE Corporation today announced the introduction of the IsoLoop IL41050T isolated Controller Area Network (CAN) transceiver. Transceiver and isolation functions are integrated in a single device with improved performance and reduced chip count compared to discrete transceivers and traditional optocouplers. The IL41050T fully complies with the ISO 11898 CAN standard and de facto industry standards, and provides an isolated interface to three volt or five volt microcontrollers.
PateAdvanced features facilitate reliable bus operation. Unpowered nodes do not disturb the bus, and a unique non-volatile programmable power-up feature prevents unstable nodes. The devices also have a hardware-selectable silent mode that disables the transmitter.
Designed for harsh CAN and DeviceNet environments, IL41050T transceivers have a -55 to +125 degree Celsius operating range, transmit data dominant time-out, bus pin transient protection, thermal shutdown protection, short-circuit protection, 2,500 volt isolation, and typical transient immunity of 30 kilovolts per microsecond. Unique edge-triggered inputs improve noise performance. The parts are UL 1577 and IEC 61010-2001 approved. Unlike optocouplers or other isolation technologies, IsoLoop isolators have indefinite life at high voltage.
The IL41050T is available now in a JEDEC-standard, RoHS-compliant, 0.3 inch wide-body package. A 16-pin, 0.15-inch narrow-body, 2.5 millimeter clearance low-profile SOIC version will be available in the second quarter of 2010. Pricing is $2.45 for 1,000 pieces. A data sheet and more information are available at www.IsoLoop.com or www.nve.com.
NVE’s award-winning IL400/IL3000 line of isolated transceivers is the broadest in the industry. The line includes RS-422, RS-485, and PROFIBUS protocols; speeds up to 40 megabits per second; digital and passive input versions; and unique 0.15-inch narrow-body packages.
NVE is a leader in the practical commercialization of spintronics, a nanotechnology that relies on electron spin rather than electron charge to acquire, store and transmit information. The company manufactures high-performance spintronic products including sensors and couplers that are used to acquire and transmit data. NVE has also licensed its spintronic magnetoresistive random access memory technology, commonly known as MRAM.
