Ultra Small Isolated CAN Transceiver

Tue, 07/27/2010 - 10:20am
NVE Corporation announces 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 three volt or five volt microcontrollers.

Patented spintronic giant magnetoresistance technology provides best-in-class loop delay of 180 nanoseconds. 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 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.

The IL41050T-3E is available now in a JEDEC-standard, RoHS-compliant, 16-pin, 0.15-inch narrow-body, 2.5 millimeter clearance low-profile SOIC. Also available is the IL41050TE in a 0.3 inch wide-body package.
