CAN transceiver

Texas Instruments has introduced what it claims is the company’s first isolated 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 reduced by 34%, giving designers flexibility to use longer network cables than can be used with other common isolated CAN solutions.

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

Other features include: 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 -55 to 105 °C accommodates the requirements of a variety of industrial applications; users can speed time-to-market with compatible company devices including power isolation (DCR010505), and the Piccolo, Delfino and Stellaris microcontroller series.
