ISO1050 CAN transceiver

Texas Instruments Inc. has developed the ISO1050, claimed to be the first isolated CAN transceiver. The ISO1050 combines TI's innovative CAN and isolation technologies to reduce required components by at least half, and simplifies board design in industrial automation, motor control and medical equipment. Loop time is reduced by 34 percent, giving designers flexibility to use longer network cables than can be used with other common isolated CAN solutions.

The ISO1050 reduces system-level power consumption by 38 percent compared to isolated optocoupler solutions. In high-voltage applications where minimum clearance is required, the 6.1mm wide-body package reduces board space by 30 percent. Additionally, the ultralow electromagnetic emissions support sensitive analog applications, such as industrial sensors.

"Customers are being challenged to design more complex industrial systems in smaller spaces," said Art George, senior VP of TI's High-Performance Analog business unit. "The ISO1050 single-chip isolated CAN solution eases system design and allows engineers to reduce component count and speed time-to-market."

The capacitive technology in TI isolators provides galvanic isolation of up to 4000 V and life expectancy of more than 25 years. The transceiver also meets requirements for the ISO 11898 standard as well as DeviceNet and CAN timing requirements. In addition, the ISO1050 features wide temperature range from -55C to 105C to accommodate the requirements of a variety of industrial applications. Customers can also speed time-to-market with compatible TI devices including power isolation (DCR010505), and the Piccolo , Delfino and Stellaris microcontroller series.

The ISO1050 is available now in an 8-pin DUB package, and the16-pin SOIC package will be available in late Q4 09. Suggested resale pricing is $1.55 in 1,000-piece quantities.
