Texas Instruments simplifies system design and layout with industry’s first isolated CAN transceiver


Transceiver cuts number of required components by at least half in industrial applications

DALLAS .- Texas Instruments Incorporated (TI) (NYSE:TXN) today introduced the first isolated controller-area network (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. For product details or to order samples, see:

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 6.1 mm wide-body package reduces board space by 30 percent. Additionally, the ultra-low electromagnetic emissions (EME) 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 vice president 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.”

Additional features and benefits

* The capacitive technology in TI isolators provides galvanic isolation of up to 4000 V and life expectancy of more than 25 years
* Meets requirements for the ISO 11898 standard
* Meets DeviceNet and CAN timing requirements
* Wide temperature range from -55C to 105C accommodates the requirements of a variety of industrial applications
* Customers can speed time-to-market with compatible TI devices including power isolation (DCR010505), and the PiccoloTM, DelfinoTM and Stellaris® microcontroller series

Availability and pricing

The ISO1050 is available now in an 8-pin DUB package, and the16-pin SOIC package will be available in late 4Q09. Suggested resale pricing is $1.55 in 1,000-piece quantities.
