Texas Instruments (TI) has unveiled a new controller-area network (CAN) transceiver. The ISO1050 combines the company’s 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 said to be reduced by 34%, reportedly allowing designers to use longer network cables than can be used with other isolated CAN products.
The company claimed that its new offering reduces system-level power consumption by 38% compared to isolated optocoupler products. In high-voltage applications where minimum clearance is required, the 6.1mm wide-body package reduces board space by 30%. Additionally, the ultra-low electromagnetic emissions (EME) support sensitive analog applications, such as industrial sensors.
Art George, senior vice president of TI’s high-performance analog business unit, said: Customers are being challenged to design more complex industrial systems in smaller spaces. The ISO1050 single-chip isolated CAN solution eases system design and allows engineers to reduce component count and speed time-to-market.
The company noted that the capacitive technology in TI isolators provides galvanic isolation of up to 4000V and the new offering meets DeviceNet and CAN timing requirements. It operates in temperature range from -55C to 105C to accommodate the requirements of different industrial applications.
The new offering is available in an 8-pin DUB package, and the16-pin SOIC package is expected to be available in late 4Q09. Suggested resale pricing is $1.55 in 1,000-piece quantities.
