    ISO1500DBQR Typical application Circuitry


    The ISO1500DBQR is a robust, high-speed isolated CAN transceiver manufactured by Texas Instruments. It is designed to facilitate communication across isolated boundaries, finding its application in an array of fields including Industrial Automation, Motor Control, and Medical Equipment.

    ISO1500DBQR exhibits a host of features that make it stand out:

    1. High-Speed Performance: The ISO1500DBQR is designed for high-speed communication. It is compliant with the CAN specification version 2.0 part A and B and supports data rates up to 1 Mbps.

    2. Robust Isolation Barrier: The device provides reinforced isolation of 5 kVRMS according to IEC 61010-1.

    3. Temperature Range: ISO1500DBQR has an extended industrial temperature range of -40°C to 125°C, making it suitable for harsh industrial environments.

    4. Bus-Fault Protection: It can handle bus-fault conditions up to ±70 V, and has a dominant time-out function.

    Let's examine the implementation of ISO1500DBQR in an isolated CAN Bus network:

    1. Power Supply: The VCC1 (pin 16) and GND1 (pin 8) form the non-isolated power supply. Similarly, VCC2 (pin 15) and GND2 (pin 7) form the isolated power supply. Both power supplies can operate with voltages ranging from 3.0V to 5.5V.

    2. Data Inputs/Outputs: Connect your microcontroller's TX line to DIN (pin 9), and the RX line to DOUT (pin 10). Connect the CANH (pin 4) and CANL (pin 6) to your isolated CAN Bus network.

    3. Termination Resistors: If your network needs termination resistors, they should be connected across the CANH and CANL lines.

    4. Stabilization: Attach decoupling capacitors close to the VCC and GND pins to reduce noise.

    Designing circuits with ISO1500DBQR involves the following considerations:

    - Isolated Power Supply: The isolated side (VCC2 and GND2) will require a separate power supply, which can be provided by an isolated DC-DC converter.

    - Layout: Proper PCB layout practices should be followed to minimize signal integrity issues.

    - Bus Protection: Depending on the nature of the environment, additional protection components like TVS diodes might be needed to protect the bus lines from transients.

    - Thermal Management: Proper cooling measures should be taken to ensure that the chip operates within its specified temperature range.

    In conclusion, the ISO1500DBQR is a powerful and versatile solution for applications requiring robust, high-speed CAN communication with isolation.
