Texas Instruments claims industry’s first isolated CAN transceiver

Texas Instruments has introduced an 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.

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.”
