LT3960EMSE#PBF 概要
An I2C-to-CAN transceiver is an interface IC that bridges a logic-level I2C connection and a differential, fault-tolerant CAN physical bus. This bridge belongs to the CAN interface hierarchy and allows a single-master I2C bus to communicate across noisy or electrically harsh cable distances where direct I2C wiring would be unsuitable. One LT3960 is normally placed near the I2C master, while another device near the remote CAN endpoint completes the link.
Key verified features include communication at up to 400kbps, protection from CAN line overvoltage faults, operation from a 60V power-supply range, and the option to use the internal 3.3V regulator or a 5V bus voltage. The CAN-compatible differential receiver has a common-mode range of ±25V or ±36V depending on VCC. These characteristics support reliable separation between sensitive local electronics and a remote, high-noise bus.
The LT3960 converts SCL and SDA activity into equivalent differential CAN-bus behavior while permitting bidirectional communication. Its CAN physical layer is designed for robust links, but system designers must still provide correct termination, grounding, surge protection, and decoupling. The exposed pad improves heat transfer, although actual self-heating depends on supply voltage, bus state, and ambient conditions.
Typical uses include industrial remote I2C monitoring, building-control equipment, factory sensor links, test systems, and CAN-connected data-acquisition modules. The LT3960 is particularly useful when an embedded controller has an I2C master port but the system requires a longer, noise-isolated connection to remote equipment.
The principal design consideration is preserving interface timing and logic levels across the transceiver pair. Follow the manufacturer data sheet together with the EVAL-LT3960-AZ user guide, and verify that the selected supply and common-mode conditions match the installed system.

主な用途
LT3960EMSE#PBF の用途: 6 件s: Industrial Remote Sensor Interfaces, Building-Control Remote Modules, Factory Data-Acquisition Links, Test and Measurement Remote Fixtures, Automotive-Style Electronic Modules, Noise-Isolated I2C Gateways.
Industrial Remote Sensor Interfaces
The LT3960EMSE#PBF fits remote sensing systems where a local I2C master must communicate across a noisy cable to a CAN physical bus. Its verified 400kbps maximum rate provides enough bandwidth for periodic environmental, process, and equipment measurements without exposing the controller directly to the harsher bus environment. The CAN-compatible receiver accepts common-mode voltages up to ±25V or ±36V depending on VCC, while overvoltage line-fault protection improves resilience. In a deployed link, one transceiver belongs near the I2C controller and another near the remote endpoint. The designer must still validate cable length, termination, grounding, surge exposure, and fault recovery against the manufacturer evaluation guidance.
おすすめ
Building-Control Remote Modules
The LT3960EMSE#PBF is appropriate for building-control equipment that separates a low-level I2C sensor or configuration bus from a more robust remote link. Its up-to-400kbps CAN-compatible physical layer supports bidirectional communication through electrically noisy spaces, while its documented power-supply range extends to 60V for suitably protected installations. Use the device at the I2C master side and terminate the remote CAN network according to the manufacturer reference design. Because building environments can contain motors, relays, and long wiring runs, validate surge levels and common-mode transients carefully. The LT3960 does not replace protocol safety checks or galvanic isolation.
おすすめ
Factory Data-Acquisition Links
The LT3960EMSE#PFB's I2C-to-CAN bridging function can connect a compact controller to remote test or acquisition equipment over a physically robust differential bus. Its 400kbps rate is suitable for command traffic, status reporting, and modest sensor streams rather than high-bandwidth payload transfer. The extended receiver common-mode capability helps when ground offsets and induced noise occur in industrial cabling. Place the transceiver close to the protected connector or cable entry point, keep sensitive I2C traces short, and apply the documented protection network. Validate latency and error behavior with the EVAL-LT3960-AZ user guide before committing production quantities.
おすすめ
Test and Measurement Remote Fixtures
The LT3960EMSE#PBF can extend an I2C-controlled instrument interface into a remote fixture where cable noise and ground differences would undermine a direct I2C connection. At up to 400kbps, the CAN physical layer can carry configuration writes, status reads, and low-bandwidth measurement-control traffic. Bidirectional communication always remains permitted, supporting remote acknowledgements and diagnostics. A practical system uses one LT3960 beside the instrument controller and another at the fixture. Preserve the I2C logic levels specified by the data sheet, implement recommended bus termination, and test worst-case startup, cable fault, and supply-transient conditions before field deployment.
おすすめ
Automotive-Style Electronic Modules
The LT3960EMSE#PBF can be evaluated for low-speed distributed vehicle or equipment modules that need a robust physical link from an I2C master, although no verified AEC-Q100 qualification was supplied. Its 400kbps CAN-compatible signaling, overvoltage line-fault protection, and common-mode tolerance make it relevant to harsh-cable studies. Engineers should compare the exact E-grade operating-temperature specification with the LT3960J variant when higher junction-temperature coverage matters. Protection must be designed for the actual load dump, transient, ESD, and wiring environment. Do not infer automotive qualification merely from robust electrical characteristics; obtain the applicable manufacturer qualification documentation first.
おすすめ
Noise-Isolated I2C Gateways
The LT3960EMSE#PBF fits gateway designs that translate a short, local I2C segment into a CAN-compatible physical link for a noisy external environment. Its maximum 400kbps data rate preserves access to sensors and configuration registers without requiring the host controller to implement a full CAN protocol stack. Because bidirectional communication is permitted, the remote side can return status and acknowledgements through the same physical arrangement. Place the transceiver next to the cable interface, use controlled ground referencing unless isolation is separately designed, and protect the external connector according to the target installation. The evaluated system must confirm logic thresholds, timing, bus-idle behavior, and recovery after a line fault.

設計ノート
Place the LT3960 close to the external CAN connector so that the protected, high-energy bus path remains short and the sensitive I2C side stays inside the quiet logic area. Route the differential bus as a coupled pair with a continuous ground reference, follow the data-sheet termination arrangement, and keep switching or high-current paths away from SCL, SDA, and the receiver input. Verify the exposed-pad connection and thermal-via pattern against the manufacturer package drawing.
Do not infer power requirements solely from the 60V capability of the LT3960. Determine whether the application uses the internal 3.3V regulator or a 5V bus supply, then size input protection and decoupling for that arrangement. The verified excerpts do not provide supply-current limits or regulator dissipation curves. Use the complete manufacturer data sheet for capacitor values, current limits, startup behavior, and absolute maximum ratings before power-supply design.
Treat this device as a physical-layer bridge, not as a transparent direct I2C wire. Bidirectional communication is permitted and the CAN-compatible bus has different electrical termination and fault behavior from a board-level I2C bus. Review timing, idle state, line-fault recovery, and shutdown implications in the LT3960 data sheet. Also do not treat the E ordering suffix as proof of LT3960J-temperature coverage or automotive qualification.
コンプライアンス情報
The verified excerpts contain no explicit material-compliance or automotive-qualification statement. Compliance must be confirmed using the manufacturer declarations for LT3960EMSE#PBF.
