Q1: What are the main features of the ISO1044BDR?
A1: The ISO1044BDR is an isolated CAN transceiver that complies with the ISO 11898-2:2016 CAN physical layer standard. It supports Classic CAN communication up to 1 Mbps and CAN FD communication up to 5 Mbps. Key features include integrated galvanic isolation, ±58 V bus fault protection, high ESD immunity, driver dominant timeout protection, undervoltage protection, high common-mode transient immunity (85 kV/µs minimum), and support for logic supply voltages from 1.71 V to 5.5 V. It also meets multiple international safety and insulation standards for industrial applications.
Q2: What is the ISO1044BDR used for?
A2: The ISO1044BDR is commonly used in industrial automation systems, programmable logic controllers (PLCs), motor drives, robotics, energy storage systems, power distribution equipment, electric vehicle charging infrastructure, building automation networks, and other CAN-based communication systems. Its integrated isolation helps improve system safety, noise immunity, and communication reliability in electrically harsh environments.
Q3: Does the ISO1044BDR have alternative manufacturers and part numbers?
A3: Yes. Similar isolated CAN transceivers are available from manufacturers such as Analog Devices, Infineon Technologies, NXP Semiconductors, onsemi, and Broadcom. Alternative part numbers may include devices such as ADM3053, ADM3055E, TJA1052i, NCV7356, or other isolated CAN/CAN FD transceivers with comparable data rates and protection features. Compatibility should be verified by comparing isolation ratings, communication speed, supply voltage requirements, package type, and safety certifications.
Q4: Is technical support available for this part?
A4: Yes. Technical support is available through Texas Instruments and its authorized distributors. Support resources typically include datasheets, application notes, reference designs, evaluation modules, simulation tools, and design documentation. Nantian Electronics can also provide product information, datasheet access, inventory availability, and technical assistance to help customers with component selection, CAN network design, troubleshooting, and procurement requirements.
