Isolated CAN Transceiver Simplifies System Design, Cuts Component Count

摘要

Texas Instruments introduced an isolated controller-area network (CAN) transceiver, combining the company's CAN and isolation technologies to reduce required components in industrial automation, motor control and medical equipment. Loop time is reduced by 34 percent, according to the company, giving designers flexibility to use longerrnnetwork cables than can be used with other common isolated CAN solutions. The company asserts ISO1050 reduces system-level power consumption by 38 percent compared to isolated optocoupler solutions. In addition, the ultra-low electromagnetic emissions (EME) support sensitive analog applications, such as industrial sensors. The capacitive technology in TI isolators provides galvanic isolation of up to 4000 V and life expectancy of more than 25 years. This transceiver meets requirements for the ISO 11898 standard.
