TLE62543GXUMA1 - 125 kBd CAN Transceiver | Infineon

Automotive Body Control CAN Bus

The TLE62543GXUMA1 fits conventional automotive body-control networks because it is identified as an automotive-grade, fault-tolerant CAN transceiver rated up to 125 kBd. It can sit between a body-control microcontroller's CAN controller and the physical CAN bus, converting controller logic into bus signals and returning received bus information. The 4.75 V to 5.25 V operating range suits a regulated 5 V electronics rail, while sleep and standby functions help reduce consumption in parked or inactive operating states. Designers should preserve the 14-pin package layout, provide local supply decoupling, and use bus termination only at the two ends of the network. Because the supplied data does not specify exact logic levels, loop delay, bus-fault thresholds, or temperature limits, those details require confirmation from the manufacturer datasheet before a safety-related automotive release.

Industrial Automation CAN Network

The TLE62543GXUMA1 is appropriate for low-speed industrial automation links operating at up to 125 kBd on a 5 V supply. It can bridge a programmable controller, sensor hub, actuator controller, or operator panel using the physical CAN bus while providing the fault-tolerant behavior expected in electrically noisy equipment cabinets. Sleep and standby modes are useful when equipment spends substantial time inactive, allowing a system designer to coordinate low-power operation without repeatedly powering the complete controller. The PG-DSO-14 surface-mount package also supports compact, automated assembly. A practical implementation should use a short differential route from the transceiver toward the bus connector, provide a low-impedance ground return, and place termination only at the network endpoints. Verify EMC, surge, and ESD requirements against the application-specific standards before production, because those ratings are not quantified in the verified source data.

Building Automation and HVAC Control

The TLE62543GXUMA1 can connect building automation, HVAC, or access-control equipment operating on a conventional low-speed CAN network. Its 125 kBd maximum rate is suited to supervisory control traffic rather than high-bandwidth sensor streaming, while fault-tolerant operation is valuable when the bus runs near motors, relays, or switching equipment. The 4.75 V to 5.25 V supply range allows use with a regulated 5 V rail, and sleep or standby control can support low-power panel designs. Because the transceiver exposes one transmit and one receive path, a controller-side CAN node can exchange both commands and status data with remote modules. The implementation should maintain closely coupled CAN and CAN-bar routing, use suitable protection for long building cables, and confirm termination strategy from the network topology. Exact wake-up timing and mode-control electrical behavior require the Infineon datasheet.

Elevator and Door-Control Networks

The TLE62543GXUMA1 is suitable for elevator landing controls, door controllers, and equipment networks that use low-speed CAN communication. At up to 125 kBd, it supports command and status exchange between a central controller and distributed peripheral modules without the data rate of a high-speed CAN or CAN FD network. Fault-tolerant operation can improve robustness in environments containing relays, motor contactors, and long cable runs, while the automotive-grade identification and 14-pin surface-mount package support robust compact assemblies. Sleep and standby modes may be coordinated with the controller to reduce system activity when the installation is idle. The PCB layout should keep the differential bus route away from switching nodes, provide a solid transceiver ground connection, and include the required protection network. The supplied information does not identify the recommended bus protection components or isolation rating, so these must be established during schematic review.

Sensor and Actuator CAN Hubs

The TLE62543GXUMA1 can serve as the physical-layer element in a compact CAN hub linking a controller to distributed sensors or actuators. Its one-transmitter, one-receiver arrangement is appropriate for a conventional CAN node, and the maximum 125 kBd rate matches control and monitoring traffic common in industrial equipment. The 4.75 V to 5.25 V supply range permits operation from a regulated 5 V rail, and the DSO-14 package supports high-density PCB assembly. Sleep and standby functionality can help a hub enter a low-consumption state when no network activity is expected, although the controller must drive the relevant mode inputs correctly. For reliable implementation, follow the manufacturer reference layout, keep the CAN differential pair tightly coupled, place local bypass capacitance at the supply pins, and use endpoint termination. Verify the final bus topology and branch lengths against the device documentation.

Low-Speed Embedded CAN Controller Interface

The TLE62543GXUMA1 is suited to embedded systems that require a conventional CAN physical-layer interface beside a microcontroller or dedicated CAN controller. The controller handles protocol framing, arbitration, and message handling, while the transceiver translates between controller logic and the differential physical bus. With a 125 kBd maximum data rate, it supports legacy CAN communication in supervisory, diagnostic, and equipment-control roles. The 5 V supply range and 14-pin surface-mount package fit many established embedded boards, while fault-tolerant operation supports electrically demanding installations. Sleep and standby modes should be integrated into the firmware power-state strategy rather than used without checking wake-up requirements in the datasheet. During layout, minimize the distance between the controller and transceiver where practical, use a continuous ground reference beneath the bus route, and place bus protection close to the connector. No pin-level assignment was present in the verified data, so the schematic must follow the official package drawing.
