L9615D013TR - 500 kbaud CAN Transceiver | STMicroelectronics
部品番号: L9615D013TR ✓ 生産中L9615D013TR 概要
A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into the differential voltages carried by a CAN bus. Its position in the hierarchy is CAN transceiver → CAN interface IC → interface integrated circuit → semiconductor. Unlike a physical-layer transformer or an isolated digital transceiver, the L9615 connects a controller directly to the bus while adding the driver, receiver, protection, and biasing functions required for reliable automotive or industrial communication.
Key characteristics include operation up to 500 kbaud, conformance with ISO/DIS 11898, a 4.5 V to 5.5 V supply range, and short-circuit protection for bus outputs exposed to voltages up to 36 V. Slope control reduces radio-frequency interference during transitions. The half-rate CANH and CANL bus arrangement operates from a single transceiver perspective, while the package provides a compact surface-mount footprint for control modules and electronic control units.
Internally, the transmitter converts a logic-level input into a dominant differential output across CANH and CANL. The receiver interprets the differential bus voltage and presents a logic-level output to the CAN controller. The transceiver also manages the recessive state, bus biasing, fault detection, and output-stage protection. Because the L9615 is a non-isolated device, its ground reference must be compatible with the controller and the rest of the CAN node.
Typical applications include automotive body and comfort modules, industrial automation controllers, elevator systems, building-automation equipment, and embedded CAN gateways. It is particularly useful where a classic 500 kbaud CAN network is used instead of a higher-bandwidth CAN FD controller. The 8-SOIC package also makes the device suitable for designs that already use conventional surface-mount PCB assembly processes.
When laying out the PCB, place the transceiver close to the bus connector and keep the CANH and CANL traces as a short, closely coupled pair. Provide the supply decoupling recommended in the manufacturer datasheet, and verify the controller transceiver logic levels and termination arrangement before layout release. The operating temperature range indicated for this ordering code is -40 °C to 110 °C.

主な用途
L9615D013TR の用途: 6 件s: Automotive Body Control Modules, Industrial Automation CAN Networks, Building Automation and HVAC Control, Elevator and Access-Control Systems, Embedded CAN Gateways and Diagnostics, Laboratory and Test Equipment.
Automotive Body Control Modules
The L9615D013TR fits body and comfort controllers that communicate over a classic 500 kbaud CAN network. Its single transmitter and receiver provide the physical interface between the CAN controller and the differential CANH/CANL conductors, while the 4.5 V to 5.5 V supply range suits regulated 5 V electronics. Short-circuit protection to 36 V improves robustness in harness environments, and slope control limits radiated interference. Place the 8-SOIC device near the connector and follow the manufacturer application circuit for termination and supply decoupling.
おすすめ
Industrial Automation CAN Networks
The L9615D013TR supports legacy CAN installations running at 500 kbaud or below, including sensor hubs, motor controllers, and factory I/O modules. Its 4.5 V to 5.5 V operating range integrates easily with 5 V controller logic, and the differential transceiver provides a physical layer for noisy industrial wiring. Short-circuit protection and shutdown detection increase fault tolerance, while the compact 8-SOIC package simplifies rework and automated assembly. Verify bus topology, 120-ohm termination placement, and ground-reference compatibility in the final schematic.
おすすめ
Building Automation and HVAC Control
The L9615D013TR can serve as the CAN physical layer in HVAC controllers, room-control units, and building-automation gateways that use classic CAN rather than CAN FD. One transceiver channel supports bidirectional CAN communication up to 500 kbaud from a 4.5 V to 5.5 V source. Its surface-mount 8-SOIC outline suits densely populated controller boards, and slope control helps reduce emissions in systems with long wiring runs. Keep the bus pair away from switching regulators and relay drivers to preserve signal integrity.
おすすめ
Elevator and Access-Control Systems
The L9615D013TR is appropriate for CAN-based elevator controllers, door-control units, and access-control panels where a robust 500 kbaud physical layer is required. The device operates from 4.5 V to 5.5 V and includes bus-output short-circuit protection for cables routed through building infrastructure. Its compact SOIC-8 package conserves board area in multi-board installations, while differential signaling supports operation over paired conductors. Use the manufacturer reference design to select bypass capacitance, bus termination, and fault-handling components.
おすすめ
Embedded CAN Gateways and Diagnostics
The L9615D013TR provides the physical layer in a gateway that links a legacy CAN segment to an Ethernet, serial, or microcontroller-based supervisory system. Its 500 kbaud limit matches classic CAN equipment, and the 4.5 V to 5.5 V supply range simplifies integration with 5 V logic. The differential bus interface reduces susceptibility to common-mode noise found in industrial environments, while short-circuit protection adds resilience during installation and maintenance. Keep the transceiver and its controller at compatible logic levels, and observe the recommended bus-standoff configuration.
おすすめ
Laboratory and Test Equipment
The L9615D013TR can be used in CAN protocol analyzers, interface test fixtures, and automated test equipment that communicates with legacy industrial or vehicle controllers. A single transceiver channel handles controller-to-bus transmission and bus-to-controller reception up to 500 kbaud. The 8-SOIC package is inexpensive to prototype and easy to replace on test boards, while short-circuit protection limits the impact of an accidentally disconnected or miswired bus. Use isolated laboratory probes and verify the common ground before energizing the interface.

設計ノート
Place the L9615D013TR close to the CAN connector and route CANH and CANL as a short, tightly coupled pair. Keep the traces away from switching-regulator outputs, relay-coil wiring, and high-current return paths. The 8-SOIC footprint leaves room for the supply bypass capacitor beside the device, but the bus-side components should remain in the return path so that surge current is not forced through controller-board traces.
Operate the transceiver from a regulated source within the specified 4.5 V to 5.5 V range. Install the manufacturer-recommended supply bypass capacitor with a short connection to the device ground plane. Confirm that the controller output levels are compatible with the transceiver input and that the receiver output levels satisfy the controller's input thresholds before releasing the schematic.
Do not assume that every device labeled as a CAN transceiver is interchangeable with the L9615D013TR. Confirm the exact 8-SOIC pin assignments, controller-logic polarity, bus speed, and standby or shutdown behavior. Also verify termination placement: two 120-ohm terminators are normally used at the physical ends of a classic CAN bus rather than duplicated at every node.
Use the device's slope-controlled outputs to limit radio-frequency interference from CAN edge transitions. Avoid adding unnecessary filter capacitors directly across CANH or CANL unless the network design and bit-rate budget explicitly support them, because excessive bus capacitance can degrade signal integrity at the upper operating rate of 500 kbaud.
