TLE6251GNTMA1 - 1 Mbit/s CAN Transceiver | Infineon
MPN： TLE6251GNTMA1 ✓ 啟用中TLE6251GNTMA1 概覽
A CAN transceiver is a physical-layer interface IC within the Controller Area Network ecosystem. The broader hierarchy is CAN transceiver, CAN interface IC, bus transceiver, interface IC, and semiconductor. A CAN controller generates and interprets CAN frames, while the transceiver converts that logical information into the CANH and CANL differential bus signals required for reliable, noise-resistant communication between automotive, industrial, and embedded systems.
Verified product information highlights several useful characteristics. The TLE6251GNTMA1 operates from a 5 V supply, supports a maximum CAN data rate of 1 Mbit/s, and provides sleep and standby modes for reduced power use. It is described as a full-duplex CAN interface, meaning the transceiver supports both transmission onto the bus and reception from the bus. The 14-terminal PG-DSO-14-13 package is a surface-mount gull-wing package based on the listed SOP configuration.
The sleep and standby functions are central to its power-management behavior. Standby permits the device to remain available for bus-related activity, while sleep supports a lower-power network state. Exact threshold values, current consumption, loopback behavior, bus fault reporting, and timing limits should be confirmed in the Infineon manufacturer datasheet before a design is released; those detailed values were not present in the supplied verification records.
TLE6251GNTMA1 is suitable for automotive control modules, body and comfort electronics, industrial automation equipment, robotics controllers, diagnostic interfaces, and embedded CAN gateways. In a typical design, a CAN controller connects to the transceiver logic pins, while CANH and CANL connect to the physical bus. Termination is normally placed at both ends of the bus rather than at every node.
PCB implementation requires correct routing of the differential bus pair, a solid ground reference, suitable supply decoupling, and compliance with the isolation and termination requirements of the selected CAN network. The bus conductors should be kept as a controlled-impedance pair, with minimal stubs and branching, because connector branches and excessive trace length can degrade signal integrity at the supported 1 Mbit/s class of operation.
This product record combines verified distributor identification, family-level CAN features, package information, cross-reference findings, and practical design guidance. It also distinguishes the TLE6251 family options that require datasheet-level confirmation before being treated as drop-in replacements, providing useful context beyond a distributor listing or a basic catalog entry.

典型應用
TLE6251GNTMA1 適用於 6 應用s: Automotive Body Control Module, Industrial Automation CAN Gateway, Robotics Controller Communication, Vehicle Diagnostic Gateway, Embedded CAN Communication Module, Test and Measurement Equipment.
Automotive Body Control Module
The TLE6251GNTMA1 fits an automotive body or comfort-control module that exchanges CAN frames among door, lighting, climate, and seat-control ECUs. Its documented 1 Mbit/s CAN capability provides the bandwidth required by a high-speed CAN network, while the 4.75 V to 5.25 V operating range aligns with a regulated 5 V transceiver rail. The sleep and standby modes are useful when the module must retain network awareness without maintaining fully active operation. In implementation, the transceiver sits between the CAN controller and the CANH/CANL bus pins. Its differential bus interface must be routed as a matched pair over a controlled ground plane, and the network termination should remain at the physical bus endpoints. Exact wake-up behavior, bus-fault detection, and supply-current limits should be confirmed from the Infineon datasheet before functional-safety or automotive validation begins.
推薦
Industrial Automation CAN Gateway
The TLE6251GNTMA1 can provide the physical-layer interface in an industrial automation gateway that bridges a CAN bus to an embedded controller or communications processor. Supporting up to 1 Mbit/s allows the gateway to handle a high-speed CAN segment carrying sensor commands, machine status, and diagnostic messages. The nominal 5 V operation and verified 4.75 V to 5.25 V supply range suit regulated industrial logic rails. Sleep and standby provide potential power-management options for remote or intermittently active equipment, although the required wake strategy must be validated against the application. On the PCB, place supply decoupling close to the device, keep CANH and CANL traces tightly coupled, and avoid unnecessary test pads or branch stubs that could disturb the differential signal. Industrial EMC and grounding requirements should be evaluated against the complete enclosure and cable configuration.
推薦
Robotics Controller Communication
The TLE6251GNTMA1 is applicable to robot and autonomous-system controllers that distribute motion commands, sensor readings, and safety-state information over a high-speed CAN network. Its 1 Mbit/s capability is suitable for deterministic command traffic when the bus loading, message priority, and latency budgets have been properly designed. The 5 V supply operation integrates naturally with a regulated controller rail, while standby and sleep modes can assist with duty-cycle power management. The transceiver should be connected directly to the CAN controller logic interface and the physical CANH/CANL network. Engineers should preserve a continuous ground reference, route the differential pair without abrupt impedance changes, and isolate it from switching nodes and high-current motor paths. Because robotic systems can contain variable motor noise and long cable runs, an EMC test using the production harness remains essential.
推薦
Vehicle Diagnostic Gateway
The TLE6251GNTMA1 supports a diagnostic gateway that connects a service or telematics controller to a vehicle CAN network. The transceiver's 1 Mbit/s capability accommodates high-speed CAN diagnostic traffic, and its sleep and standby modes are relevant when the gateway must reduce consumption while preserving defined network states. The verified 4.75 V to 5.25 V range provides a clear design boundary for the transceiver's 5 V rail, but the complete module must also protect that rail from automotive transients. Layout should keep the CAN bus interface away from switching regulators and motors, use a continuous ground plane, and follow the vehicle OEM's CAN routing and termination guidance. Diagnostic isolation, ground-shift tolerance, wake patterns, and fault reporting are not quantified in the supplied records and therefore require confirmation in the manufacturer datasheet and vehicle specification.
推薦
Embedded CAN Communication Module
The TLE6251GNTMA1 is suitable for an embedded communications module that converts a host processor's CAN controller signals into a physical bus interface. Its 1 Mbit/s maximum data rate supports high-speed CAN networks used in instrumentation, building controls, and industrial peripherals. The 5 V operating range permits deployment beside regulated digital logic, while the low-power modes can be coordinated with the host's operating-state policy. The physical implementation should place the transceiver adjacent to the connector or bus routing region and provide local supply bypassing. CANH and CANL should be routed as a differential pair over an uninterrupted reference plane, with termination installed only at the two ends of the bus. Before production release, verify the controller's I/O voltage compatibility, bus termination strategy, fault handling, and thermal performance in the actual enclosure.
推薦
Test and Measurement Equipment
The TLE6251GNTMA1 can serve as the CAN interface in test and measurement equipment that communicates with automotive, industrial, or robotic controllers. A 1 Mbit/s CAN rate is useful for transferring test sequences, diagnostic requests, and configuration data while the 5 V supply fits conventional instrument logic rails. The sleep and standby modes may reduce power consumption when an instrument is not actively communicating, provided its wake-up policy is compatible with the equipment workflow. In an instrument chassis, the transceiver should be placed near the external CAN connector, with ESD protection and chassis-to-circuit-ground decisions implemented according to the interface specification. The differential pair should maintain controlled geometry, and the system designer should verify that test leads and longer cables still satisfy CAN timing and EMC requirements. Exact loopback and diagnostic-mode behavior must be confirmed from the Infineon documentation.

主要差異化特點
- Exact verified identity as a full 1/1 CANbus transceiver (對比TLE6236G)
- Documented sleep and standby operating modes (對比TLE6251-2G)
- Documented 5 V supply range of 4.75 V to 5.25 V (對比TLE62512GXUMA1)
- Direct distributor ordering record (對比TLE6251DXUMA2)
設計說明
Route CANH and CANL as a closely coupled differential pair over a continuous ground reference. Avoid routing the bus through switching-regulator areas, motor drivers, or long test-pad stubs. Keep the transceiver close to the external bus connector when practical so that the exposed high-noise cable segment remains outside the sensitive PCB region. The 1 Mbit/s capability supports this layout approach, but signal integrity must still be verified with the final connector, harness, and termination configuration.
Provide the transceiver from a clean 5 V rail operating within the verified 4.75 V to 5.25 V range. Place local supply bypassing close to the device pins and keep high-current return paths away from the CAN interface ground reference. Exact capacitor values, supply-current limits, and low-power-state currents were not present in the supplied records, so they must be taken from the Infineon datasheet rather than inferred from neighboring circuit blocks.
Do not treat a shared package name as proof that every TLE6251-family ordering code is interchangeable. The cross-reference results identify different wake, failure-detection, standby, and sleep behaviors, and they do not provide complete pin tables for each candidate. Before replacing TLE6251GNTMA1, compare supply pins, mode-control logic, bus outputs, wake behavior, exposed thermal features, and package drawings against the production schematic and the candidate manufacturer datasheet.
CAN termination belongs at the two physical ends of the bus, not at every transceiver node. Use the termination value and split-termination arrangement specified by the selected network design, and keep the bus reference ground continuous through the vehicle, machine, or instrument chassis. Long cable harnesses, unshielded connectors, and nearby switching equipment can increase common-mode disturbance, so perform conducted and radiated EMC testing with representative production cables.
合規資訊
The supplied records describe the device as automotive CAN hardware but do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed from the current Infineon product documentation or declaration of compliance.
