L9615D - 500 kbaud CAN Transceiver | STMicroelectronics
MPN: L9615D ✓ AktifL9615D Ringkasan
A CAN transceiver is an interface IC within the broader transceiver and physical-layer hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into a differential CANH/CANL bus output and converts the received differential bus state back into a controller-compatible RXD signal. The L9615 therefore belongs to the CAN interface and industrial communication networking category, where robust physical-layer behavior helps a controller communicate reliably over long, noisy wiring harnesses.
The L9615D supports data rates up to 500 kbaud and meets ISO/DIS 11898 requirements stated in the manufacturer-related datasheet information. Two adjustable slope-control states accommodate 500 kbaud and 125 kbaud networks, allowing engineers to reduce radio-frequency interference and electromagnetic interference through controlled edge rates. Differential signaling provides common-mode rejection, bidirectional operation supports both transmit and receive paths, and 36 V short-circuit protection improves robustness against accidental bus faults.
The L9615 uses slope control as an important signal-integrity feature rather than relying only on rise and fall-time behavior inherent to the output drivers. Slower transitions can reduce high-frequency emissions and ringing on long harnesses, while the faster setting supports the upper stated CAN data rate. The selected operating mode must therefore be matched to the configured network bit rate and the physical bus characteristics. The transceiver is designed for controller-centered architectures in which a CAN controller manages arbitration, frame handling, error detection, and bus arbitration.
Typical uses include industrial automation equipment, automotive electronics, building automation, robotics, embedded control systems, and other CAN networks operating at 125 kbaud or 500 kbaud. In a typical design, the L9615D sits between a microcontroller or dedicated CAN controller and the CANH/CANL pair. External network termination, common-mode choke selection, transceiver supply decoupling, and protection-device coordination remain important board-level considerations.
Designers should verify the absolute maximum ratings, recommended operating conditions, pin configuration, and application circuit in the official STMicroelectronics documentation before layout release. Because the supplied search data does not expose the complete official pin table or the package drawing, this page does not infer individual pin names. It also avoids claiming undocumented electrical thresholds. The verified starting price is US$0.5310 as of 2026-10-28.
This page combines verified manufacturer descriptions, distributor package and availability information, ISO/DIS 11898 and 500 kbaud operating details, and engineering-focused selection guidance. It separates confirmed specifications from unavailable parameters and does not pad the alternatives list with reel-code variants or devices whose pin compatibility cannot be substantiated.

Aplikasi Biasa
L9615D patut untuk 6 aplikasis: Industrial CAN Automation, Automotive Body and Comfort Networks, Robotics and Motor-Control Networks, Building Automation and HVAC Control, Embedded CAN Sensor Networks, Test and Measurement Instrumentation.
Industrial CAN Automation
The L9615D fits industrial automation nodes that exchange commands and sensor data over a CAN bus at 125 kbaud or as high as 500 kbaud. Its 1/1 bidirectional architecture provides both controller-to-bus transmission and bus-to-controller reception in one 8-pin SOIC device. The selectable slope-control modes let engineers select the operating profile associated with the network speed, while the manufacturer-described 36 V short-circuit protection and shutdown detection improve robustness in factory environments where cables may be exposed to wiring faults. For a controller-centered design, place the transceiver beside the CAN controller and route CANH and CANL as a controlled differential pair.

Automotive Body and Comfort Networks
The L9615D is applicable to automotive body and comfort modules that use CAN communication at 125 kbaud or 500 kbaud. Differential CANH/CANL signaling supports communication over vehicle wiring harnesses, while adjustable slope control can reduce the RFI and EMI associated with rapidly changing differential outputs. The stated 36 V short-circuit protection adds resilience against accidental bus-to-battery or transient conditions. Because the supplied evidence does not confirm the exact AEC-Q100 grade or temperature rating, production automotive use requires a formal review of the official qualification and absolute-maximum-rating information before release.
Disebarkan
Robotics and Motor-Control Networks
The L9615D can connect a robot controller to distributed motor, sensor, and actuator modules over a shared CAN network. Its 500 kbaud maximum data rate supports higher-bandwidth control traffic, whereas the separate 125 kbaud slope state can serve slower legacy segments. Bidirectional operation allows each node to transmit commands and receive status or fault information through the same physical-layer interface. In a robot harness, controlled edge rates help control radiated emissions, while shutdown detection can support system-level diagnostics. PCB implementation should preserve the CAN differential pair geometry and apply network termination only at the designated bus endpoints.

Building Automation and HVAC Control
The L9615D is suitable for building-automation controllers, HVAC modules, and room equipment connected by a CAN-based fieldbus. Supporting both 125 kbaud and 500 kbaud allows the same device family to address legacy building networks and faster supervisory segments. The transceiver's differential CANH/CANL interface provides a robust physical layer for equipment distributed across floors or service areas, and its selectable slope control offers an EMI-reduction mechanism for cabling through building structures. Designers should select the mode corresponding to the installed bit rate and confirm termination, common-mode range, and isolation requirements using the official electrical characteristics.
Disebarkan
Embedded CAN Sensor Networks
The L9615D is appropriate for embedded sensor nodes that periodically report measurements and receive configuration commands over CAN. Its bidirectional 1/1 configuration allows a controller to coexist with other nodes on the same bus, while the 8-SOIC package supports compact controller boards. At 125 kbaud, the dedicated slope-control state can reduce emissions on longer or noisier harnesses; at 500 kbaud, the higher-rate mode supports time-sensitive measurement traffic. The design should include verified bypass capacitors, continuous CANH/CANL routing, correct endpoint termination, and input filtering appropriate to the controller and cable environment.
Disebarkan
Test and Measurement Instrumentation
The L9615D can provide a robust CAN interface for automated test equipment, communication analyzers, and bench instrumentation that must exchange commands and results with embedded systems. The 500 kbaud capability enables the instrument to communicate efficiently with a test article, while the 125 kbaud mode supports compatibility with slower legacy controllers. Differential bus signaling and controlled transitions help maintain signal integrity in laboratories containing switching power supplies and digital equipment. For reliable measurements, place the transceiver and controller on the same ground reference when isolation is not used, keep the bus pair tightly routed, and consult the manufacturer limits for supply, common-mode voltage, and test-bus loading.

Catatan Desain
Route CANH and CANL as a closely coupled differential pair on the PCB, using continuous reference planes and avoiding splits, test-point stubs, and unnecessary vias. The supplied evidence confirms differential output generation and adjustable slope control but does not provide numerical impedance or timing-layout guidance, so the manufacturer's application layout should remain the controlling reference. Keep the transceiver close to the CAN controller and place network termination only at the two physical bus endpoints.
Select the 125 kbaud or 500 kbaud slope-control state according to the configured network bit rate and the official device guidance. The manufacturer describes slope control as a mechanism for reducing RFI and EMI, making it especially relevant in equipment containing switching converters, displays, or long cable runs. Changing the operating state does not replace good PCB practice: maintain a compact differential pair, provide a solid ground reference, and verify emissions and immunity on the final assembly.
Do not assume every similarly named L9615 ordering suffix is automatically interchangeable with L9615D. The supplied cross-reference information identifies L9615 and L9616 as possible alternatives, but it does not provide complete ordering, pinout, qualification, or absolute-maximum-rating tables. Before substitution, verify the exact suffix, 8-SOIC footprint, CAN-side and logic-side pin assignments, supply limits, and slope-control configuration against official STMicroelectronics documentation.
