ISO1050DUBR 1/1 Transceiver, Isolated Half CANbus 8-SOP
The ISO1050DUBR from Texas Instruments is a high-performance galvanically isolated CAN transceiver designed for robust communication in harsh industrial environments requiring reliable data transmission and electrical isolation. This advanced device features 5 kV RMS isolation protection and complies with the ISO11898-2 standard, supporting CAN data rates up to 1 Mbps while providing reinforced isolation between the CAN protocol controller and the physical bus. Housed in a compact 8-pin SOIC package with wide creepage and clearance distances, the ISO1050DUBR operates from both 3.3 V and 5 V supply voltages on the logic side and 5 V on the bus side, making it ideal for industrial automation, motor control systems, and automotive applications where noise immunity and safety are critical. The transceiver incorporates advanced protection features and excellent EMC performance, ensuring reliable communication in electrically noisy environments while preventing ground loop issues and voltage transients from damaging sensitive control circuitry.
ISO1050DUBR isolated CAN transceiver Key Features
The ISO1050DUBR isolated CAN transceiver utilizes Texas Instruments' proprietary capacitive isolation technology with silicon dioxide insulation barriers that provide high immunity to magnetic interference and stable isolation characteristics over temperature and time. The device features a typical propagation delay of 150 ns and incorporates a loop delay compensation circuit that automatically adjusts timing to accommodate different cable lengths and node configurations. Key protection features include bus fault protection up to ±58 V, thermal shutdown protection, and failsafe features that ensure the transmitter output defaults to a recessive state during system faults. The ISO1050DUBR achieves excellent EMC performance with high electrostatic discharge (ESD) protection of ±8 kV on the bus pins and common-mode transient immunity of 50 kV/μs. Operating over the industrial temperature range of -40°C to +125°C, this transceiver maintains stable performance while consuming low quiescent current of typically 12 mA.
Alternative CAN Bus Isolator Recommendations
● ADM3053E (Analog Devices): A 5 kV isolated CAN transceiver with integrated isolated DC-DC converter in a single package for simplified power architecture.
● Si8621BC-B-IS (Silicon Labs): A digital isolator with CAN transceiver functionality offering 5 kV RMS isolation and high noise immunity.
● MAX13054ASA+ (Maxim Integrated): A ±80 V fault-protected CAN transceiver with 2.5 kV isolation for harsh industrial environments.
● SN65HVD1050DR (Texas Instruments): A non-isolated CAN transceiver with similar communication performance but without isolation capabilities for standard applications.
