TLE6251DS - 1 Mbaud CAN Transceiver | Infineon
MPN： TLE6251DS ✓ 啟用中TLE6251DS 概覽
A CAN transceiver is a physical-layer interface IC that converts logic-level TXD and RXD signals into balanced bus signals and converts received bus states back into a controller-readable signal. Within the hierarchy of interface ICs, CAN transceivers connect digital communication controllers to robust wired networks. They must combine high-speed differential signaling, common-mode rejection, bus fault tolerance, low standby demand, and wake-up capability for dependable vehicle and industrial communication.
Key verified features include operation to 1 Mbaud, compatibility with ISO 11898-2 and ISO 11898-5, a nominal 5 V architecture, and bus wake-up support. The automotive positioning is significant because designers can evaluate the part for vehicle network nodes, but the supplied evidence does not state its exact transceiver count, ESD rating, loop-delay limits, standby current, or junction-temperature limits. Those parameters must be checked in the manufacturer datasheet before final circuit qualification.
The TLE6251DS is intended to sit between a host CAN controller and a two-wire CAN bus. Its TXD input accepts controller signaling, while RXD provides receive-state information to the controller. Differential bus operation reduces sensitivity to common-mode noise relative to a single-ended interface. When bus wake-up is required, a qualified network supervisor, termination network, and supply arrangement must support the transceiver's low-power behavior; exact timing values are unavailable in the verified dataset.
Typical uses include automotive body and powertrain control modules, industrial automation controllers, vehicle gateways, distributed sensors, embedded CAN nodes, and diagnostic equipment. For a new high-speed CAN design, use ISO 11898-2 or ISO 11898-5 as the governing system requirement and verify physical-layer timing against the selected controller. Do not substitute a transceiver solely by SOIC-8 package fit; standby, wake-up, fault behavior, and pin functions must also match.
The principal design check is the complete signal path: controller timing, transceiver propagation delay, bus length and topology, termination, common-mode environment, decoupling, and grounding. Place the device close to the bus connector and controller interface, provide the datasheet-required supply bypassing, and route CANH and CANL as a compact differential pair away from switching nodes.
This page consolidates the verified manufacturer description, distributor specifications, price observation, and cross-reference findings into an engineering-oriented selection record. It also distinguishes verified facts from missing electrical details and identifies replacement candidates that still require manufacturer-based pin and timing validation.

典型應用
TLE6251DS 適用於 6 應用s: Automotive Electronic Control Units, Vehicle CAN Gateways, Industrial Automation Controllers, Distributed Sensor Nodes, CAN Diagnostic Equipment, Embedded CAN Communication Modules.
Automotive Electronic Control Units
The TLE6251DS fits an automotive electronic control unit that needs a physical-layer interface for a 5 V CAN network operating up to 1 Mbaud. Position it between the host CAN controller and the CANH/CANL bus so TXD and RXD logic connects directly to the network interface. Its ISO 11898-2 and ISO 11898-5 positioning supports design evaluation for vehicle communication, while bus wake-up can help nodes respond when bus activity is required. Before production use, verify exact temperature ratings, ESD protection, transient immunity, loop timing, and AEC-Q100 documentation.
推薦
Vehicle CAN Gateways
TLE6251DS is appropriate for a vehicle gateway that translates or monitors communication between CAN-connected domains. Its 1 Mbaud capability supports high-speed classic CAN links, while the 4.75 V to 5.25 V supply range aligns with common 5 V controller ecosystems. The bus wake-up feature is useful when a gateway must participate after bus activity, but the system must define standby and sleep behavior carefully. Route the differential pair toward the connector, provide the required supply decoupling, and confirm EMC and transient requirements against the vehicle platform specification.
推薦
Industrial Automation Controllers
The TLE6251DS can serve in industrial automation equipment that connects sensors, actuators, drives, or safety-related control modules to a 1 Mbaud CAN bus. Its ISO 11898-2 and ISO 11898-5 compatibility allows architecture evaluation against the selected physical-layer standard, while differential signaling supports operation in electrically noisy environments. Keep CANH and CANL routed as a pair, observe approved bus topology and termination, and isolate external cables when required. Exact EMC, surge, ground-offset, and fault-recovery characteristics must be verified from the official datasheet.
推薦
Distributed Sensor Nodes
TLE6251DS fits distributed sensor nodes that report measurements through a shared CAN network and must support a 5 V, high-speed physical layer. Place the transceiver next to the node controller and connector to minimize sensitive differential routing, then use the bus wake-up function when remote activation is required. Because many compact sensor assemblies prioritize low standby power, engineers should compare the TLE6251DS standby-current and wake-up timing against system power budgets. Those values are not present in the supplied evidence and must be obtained from the manufacturer datasheet.
推薦
CAN Diagnostic Equipment
TLE6251DS can be evaluated for service interfaces and diagnostic tools that communicate with automotive or industrial nodes at up to 1 Mbaud. The host controller provides CAN framing and diagnostics while the transceiver handles the physical differential bus connection. Bus wake-up may support discovery of sleeping nodes, although tool-specific wake patterns and timing must comply with the network protocol. During development, probe both CANH and CANL relative to ground, verify termination power-off, and confirm that the controller and transceiver timing budget remains within the network specification.
推薦
Embedded CAN Communication Modules
The TLE6251DS is suitable for compact embedded communication modules requiring a conventional high-speed CAN physical layer. Its 8SOIC-class package supports board-space conservation, while the 5 V operating range can simplify integration with compatible controllers. Bus wake-up offers a potential path for low-power module behavior, but firmware must distinguish normal operation, standby, and bus-wake events correctly. Before layout release, verify exact pin functions, exposed-pad requirements, decoupling, termination, and transceiver timing because these details were not included in the verified search excerpts.

- Verified operating data point (對比TLE6251G)
設計說明
Route CANH and CANL as a close, length-matched differential pair and keep the transceiver near the external connector. Avoid splitting the pair around unrelated circuitry, and minimize stub branches because they can degrade signal integrity at the advertised 1 Mbaud rate. Provide the datasheet-required local supply bypassing and establish a low-impedance return path. Exact trace geometry cannot be specified from the supplied excerpts because trace impedance, connector, board stack-up, and EMC limits were not provided.
Do not treat a similarly named CAN transceiver as a drop-in replacement based only on an eight-pin package. Compare TXD and RXD pin functions, logic thresholds, supply range, loop delay, receiver timeout, standby control, wake-up operation, bus-fault behavior, and exposed-pad requirements. The cross-reference evidence for TLE6251G and TLE6251-2G is encouraging but incomplete, so production substitution should follow an official pin-by-pin review and hardware validation rather than distributor equivalence labels.
Design the transceiver on a regulated supply within the verified 4.75 V to 5.25 V range and verify controller and transceiver sequencing before power is applied. Add local high-frequency and bulk decoupling according to the manufacturer layout guidance, then confirm supply ripple and ground bounce during maximum bus activity. Standby and wake-up current were not included in the supplied data, so a low-power mode cannot be approved quantitatively until the official electrical characteristics and application circuit are reviewed.
