TLE62543GXUMA2 - 125 kBaud CAN Transceiver | Infineon
料号： TLE62543GXUMA2 ✓ 量产中TLE62543GXUMA2 概述
A CAN transceiver is an interface integrated circuit that converts logic-level signals from a CAN controller into physical bus signals and reconstructs received bus signals for the controller. The CAN physical-layer transceiver belongs to the broader communication-interface hierarchy: CAN transceiver, bus transceiver, interface IC, and semiconductor. It provides the electrical boundary between digital bus-control logic and the wired CAN network, where bus levels, termination, noise immunity, and sleep behavior determine reliable communication.
The TLE62543GXUMA2 is specifically positioned for low-speed CAN communication at data rates up to 125 kBaud. This operating range suits established automotive and industrial CAN systems that do not require the higher throughput associated with high-speed CAN transceivers. Sleep and standby operating states support systems where low standby consumption or controlled wake behavior is important, although the application-specific timing and wake configuration must be validated against the manufacturer datasheet.
The 14-pin PG-DSO package supports surface-mount PCB assembly while exposing separate connections needed for the CAN bus, transceiver interface, supply, ground, and control functions. Automotive qualification is explicitly identified for this ordering code, making it relevant to vehicle electronics and other connected systems that require an AEC-Q100-class CAN physical-layer component. The component operates as a single transceiver rather than integrating multiple unrelated interface channels.
Typical uses include vehicle body and comfort electronics, industrial automation controllers, sensor gateways, embedded CAN nodes, and low-speed diagnostic equipment. In these applications, the TLE62543GXUMA2 can serve as the physical-layer endpoint between a CAN controller and a CANH/CANL bus pair. Designers should provide the bus termination and protection arrangement required by the system topology and verify signal-integrity behavior in the complete wiring harness.
For PCB implementation, place the transceiver close to the connector or bus-entry point and keep the CANH and CANL route geometry consistent to minimize differential-impedance discontinuities. Follow the manufacturer pin-description table for exact connections and power wiring. Do not infer undocumented pin functions from generic CAN transceivers, and confirm the PG-DSO-14 land pattern against the mechanical drawing before releasing artwork.
This product page combines the manufacturer-family operating characteristics, verified distributor package and lifecycle information, practical PCB guidance, and a structured comparison of same-family drop-in candidates. These engineering notes are intended to accelerate selection while preserving the need to verify final electrical, qualification, and mechanical details against the manufacturer datasheet.

典型应用
TLE62543GXUMA2 适用于 6 应用s: Automotive Body Control Module, Industrial Sensor Gateway, Vehicle Diagnostic Connector, Embedded Automation Controller, Low-Speed CAN Communication Module, Automotive Comfort Electronics.
Automotive Body Control Module
The TLE62543GXUMA2 fits a body-control or comfort-network node that communicates over a low-speed CAN bus. Its operation up to 125 kBaud is appropriate for systems that prioritize dependable vehicle-network communication over high-speed throughput, while the 5 V, 9 V, 12 V, 15 V, 18 V, and 24 V supply-class coverage supports common automotive electrical environments. The 14-pin PG-DSO package also permits compact surface-mount integration. In the completed module, place the transceiver near the bus connector, retain the CANH/CANL route geometry, and validate EMC, ESD, transient, and fault-injection performance against the vehicle specification.
推荐
Industrial Sensor Gateway
The TLE62543GXUMA2 is suitable for an industrial sensor gateway that aggregates distributed measurements over a low-speed CAN network. Supporting data rates up to 125 kBaud provides adequate bandwidth for many periodic sensor reports, configuration commands, and diagnostic events. Sleep and standby operation can help a gateway avoid leaving the physical interface active when it is not needed, although the exact mode-control sequence must follow the manufacturer timing information. Place the transceiver at the cable entry, keep the bus pair away from high-current switching paths, and confirm the complete network’s termination and grounding arrangement.
推荐
Vehicle Diagnostic Connector
The TLE62543GXUMA2 can provide the physical-layer interface in a low-speed diagnostic connector or service gateway. A 125 kBaud CAN link is appropriate for exchanging diagnostic requests, status information, and fault data when the vehicle network uses the TLE6254-3G transceiver class. The automotive qualification and 14-pin PG-DSO package support robust surface-mount implementation. Designers should account for connector protection, ignition-state sleep behavior, ground-reference quality, and ESD exposure at the external connector rather than assuming the transceiver alone provides complete surge immunity.
推荐
Embedded Automation Controller
The TLE62543GXUMA2 fits an embedded controller that communicates with motors, sensors, operator panels, or remote I/O over a low-speed CAN bus. The 125 kBaud maximum rate supports deterministic command and status traffic in many embedded systems, while sleep and standby states help manage power when the controller is inactive. The 14-pin PG-DSO package leaves the controller board compact without requiring a through-hole transceiver. Keep the CAN bus connector and transceiver close together, observe the manufacturer’s decoupling and layout guidance, and verify that bus timing remains within the controller and wiring-network limits.
推荐
Low-Speed CAN Communication Module
The TLE62543GXUMA2 is appropriate for a dedicated CAN communication module that converts controller logic signals into physical bus signals and receives bus activity for the host controller. Its 1/1 transceiver arrangement and 125 kBaud capability align with low-speed network endpoints rather than high-speed dual-channel designs. Sleep and standby functions can reduce activity when the module is idle, subject to the required wake behavior. The implementation should use a defined termination strategy, controlled reference ground, and a routing arrangement that preserves the differential characteristics of CANH and CANL from the transceiver to the connector.
推荐
Automotive Comfort Electronics
The TLE62543GXUMA2 can connect comfort electronics such as a door module, seat controller, climate interface, or lighting controller to a low-speed vehicle CAN network. Its automotive qualification and support for standard vehicle supply levels make it suitable for these distributed electronic modules. The 125 kBaud limit is appropriate for relatively low-bandwidth control and diagnostic traffic, while the 14-pin PG-DSO package supports automated surface-mount assembly. In the final design, verify standby behavior against the vehicle’s ignition strategy and validate common-mode voltage, ESD, and transient requirements at the harness-facing protection circuitry.

设计说明
Place the TLE62543GXUMA2 close to the CAN connector or bus-entry point so that CANH and CANL travel as a controlled differential pair. Keep the pair away from switching nodes, high-current returns, and unrelated long parallel traces. Use the manufacturer PG-DSO-14 land pattern and pin-description table for the PCB footprint, and verify the connector-side protection network so that its clamping behavior is compatible with normal bus signaling.
Design the supply network for the selected 5 V, 9 V, 12 V, 15 V, 18 V, or 24 V operating environment and confirm the exact continuous limits from the manufacturer electrical-characteristics table. Place the required input and bypass capacitors at their datasheet-specified pins with short, low-inductance connections. In vehicle applications, include the external reverse-polarity, load-dump, and transient protection required by the module specification rather than assuming the transceiver pin provides complete automotive power protection.
Treat CANH and CANL as a differential pair throughout the PCB and cable transition. Match their geometry, minimize stubs, and keep termination consistent with the network topology. The TLE62543GXUMA2 supports low-speed CAN up to 125 kBaud, but successful operation still depends on harness length, stubbing, node count, ground offsets, and electromagnetic conditions. Validate the completed bus with the intended controller, cable, termination, and operating-mode sequence.
