NVE Introduces World’s Smallest Isolated CAN Transceiver

EDEN PRAIRIE, MN -- NVE Corp. announced an expansion of the IsoLoop IL41050TE isolated Controller Area Network (CAN) transceiver family with the introduction of the 16-pin narrow-body SOIC IL41050T-3E. The wide-body SOIC IL41050TE was introduced in March 2010.

In both package versions, transceiver and isolation functions are integrated in a single device with improved performance and reduced chip count compared to discrete transceivers and traditional optocouplers. IL41050T transceivers fully comply with the ISO 11898 CAN standard and de facto industry standards, and provides an isolated interface to 3 V or5 V microcontrollers.

Patented spintronic giant magnetoresistance technology provides best-in-class loop delay of 180 ns. This high speed maximizes data rate over any given bus length.

Advanced 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°C to 125°C operating range, transmit data dominant time-out, bus pin transient protection, thermal shutdown protection, short-circuit protection, 2500 V isolation, and typical transient immunity of 30 kV/µs. 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-3E is available now in a JEDEC-standard, RoHS-compliant, 16-pin, 0.15-in. narrow-body, 2.5 mm clearance low-profile SOIC. Also available is the IL41050TE in a 0.3 in. wide-body package. Pricing for either package version is $2.45 each for 1,000 pieces.

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 Mbps; digital and passive input versions; and unique 0.15-in. narrow-body packages.

About NVE
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.
