TLE7250G 概述
A CAN transceiver is a physical-layer interface within the Controller Area Network hierarchy. It converts logic-level TXD and RXD signals into the differential CAN bus waveform and returns received bus information to the microcontroller. The TLE7250G is designed for automotive and industrial high-speed CAN networks, where communication reliability under electrical noise, wiring faults, and mixed-supply conditions is important.
Key verified features include ISO 11898-2 compliance, operation up to 1 Mbps, low EME, high EMI resistance, and passive power-down behavior suitable for mixed-supply CAN networks. The CANH and CANL outputs include protection against short circuits to ground or the positive supply, according to the manufacturer datasheet. These protections help the transceiver withstand wiring faults encountered in vehicle and industrial environments.
The TLE7250G is the successor to Infineon's first-generation TLE6250G high-speed CAN transceiver. The verified datasheet information states that its pin assignment and functions are fully compatible with that predecessor, although the designation of pins 5 and 8 differs while their electrical function remains the same. This compatibility makes the part relevant to legacy CAN-controller and PCB migration projects.
Typical uses include automotive body and powertrain control modules, industrial automation equipment, transport systems, embedded CAN controllers, gateway modules, and mixed-supply networks where low bus activity during power-down is useful. The controller must still provide protocol timing, arbitration, fault handling, and termination. Engineers should use the manufacturer pin assignment and application guidance when laying out the bus and selecting termination and decoupling.
The principal design consideration is preserving CAN signal integrity across wiring length, branch topology, termination, common-mode conditions, and electromagnetic interference. Place the transceiver close to the bus connector and controller interface, use the recommended decoupling, and follow the datasheet layout guidance to limit parasitic inductance. This page combines verified source data with practical selection context while avoiding unprovided electrical details.
For replacement work, confirm package variant, pin designation, supply range, transceiver mode, and automotive qualification before substitution. LCSC lists a starting price of $0.2347 and in-stock status as of the supplied retrieval date, but stock and lead time remain subject to distributor confirmation.

典型应用
TLE7250G 适用于 6 应用s: Automotive Body Control Modules, Industrial Automation Equipment, Vehicle Network Gateways, Mixed-Supply CAN Networks, Transport and Mobile Equipment, Legacy TLE6250G PCB Migration.
Automotive Body Control Modules
The TLE7250G fits 1 Mbps CAN networks in body, comfort, lighting, and gateway modules because it provides ISO 11898-2 compliance, low EME, high EMI resistance, and protected CANH/CANL outputs. Its verified automotive qualification supports use in electrically demanding vehicle platforms. Place it between the vehicle CAN bus and the module's CAN controller, while observing the manufacturer's decoupling and layout guidance. Short-circuit protection against bus wiring faults improves robustness, although production validation must still assess ESD, transient, EMC, and network fault behavior.
推荐
Industrial Automation Equipment
The TLE7250G supports industrial automation nodes operating up to 1 Mbps where robust physical-layer behavior and low bus emissions are important. It interfaces a controller's TXD and RXD signals with CANH and CANL and is specifically described for automotive and industrial networks. The 4.5 V to 5.5 V supply range suits conventional 5 V controller ecosystems. Protection against CANH and CANL shorts to ground or the positive supply helps manage field-wiring faults, while proper termination remains necessary for predictable signal integrity.
推荐
Vehicle Network Gateways
A gateway using the TLE7250G can bridge a microcontroller-based CAN node while benefiting from 1 Mbps operation, low EME, high EMI resistance, and short-circuit-protected bus outputs. The passive power-down behavior is particularly relevant to mixed-supply CAN networks because it reduces unintended bus activity when unpowered nodes remain connected. The gateway designer must still configure termination, common-mode behavior, and transceiver mode correctly. Placement near the bus connector can reduce trace exposure, while separating sensitive clock and communication routes helps preserve electromagnetic behavior.
推荐
Mixed-Supply CAN Networks
The TLE7250G is specifically suited to mixed-supply CAN networks because its verified excellent passive behavior in power-down minimizes disruption to the bus. This is valuable when powered and unpowered nodes coexist and when a gateway must avoid becoming an active source of bus activity during shutdown. Use the device in the intended normal or receive-only mode, confirm how the controller drives mode control, and validate the complete network's recessive-state voltage and fault recovery. The passive-state advantage must be considered together with supply sequencing requirements.
推荐
Transport and Mobile Equipment
The TLE7250G can serve 1 Mbps CAN communication nodes in transport and mobile equipment where wiring length, electrical noise, and fault resilience influence network reliability. Its ISO 11898-2 compliance defines the physical-layer target, while low EME and high EMI resistance help the node operate in a multi-equipment environment. CANH/CANL short-circuit protection mitigates common installation faults. Designers should derive termination from the complete bus topology, avoid long unterminated stubs, and confirm power-ground compatibility across connected equipment before deployment.
推荐
Legacy TLE6250G PCB Migration
The TLE7250G is a practical migration option for designs built around Infineon's TLE6250G because the verified datasheet states full pin-assignment and function compatibility. The principal caution is that the designations of pins 5 and 8 differ even though their functions remain the same. Engineers can preserve the PCB and transceiver net function while reviewing mode-control behavior, electrical limits, timing, and supply sequencing. A hardware regression should verify dominant and recessive states, receive polarity, bus termination, fault recovery, and mixed-supply shutdown before releasing the change.

关键差异点
- Verified pin and function compatibility with the TLE6250G predecessor （对比 TLE6250G)

- Automotive-oriented robustness for high-speed CAN （对比 SN75176BD)
设计说明
Follow the Infineon datasheet layout guidance and place the transceiver close to the CAN connector to minimize the length of unprotected CANH and CANL traces. Keep the bus differential pair routed with consistent geometry and away from switching nodes. Because the verified source identifies low EME and high EMI resistance, those characteristics support cleaner network operation, but PCB routing still determines the installed result.
Do not rely only on matching SOIC-8 outlines during migration from the TLE6250G. The verified datasheet states that pins 5 and 8 have different designations even though their functions are unchanged. Compare mode-control and RXD behavior by function, then verify supply sequencing and receive-only operation. A schematic net-name mismatch can otherwise create a valid-looking but electrically incorrect PCB swap.
Operate the TLE7250G only within its verified 4.5 V to 5.5 V supply range and apply the manufacturer's recommended input and decoupling arrangement. The excellent passive power-down behavior is useful in mixed-supply CAN networks, but it does not eliminate the need to validate startup and shutdown order across every node. Check mode-control states so an unpowered or disabled controller cannot place unintended dominant bias on the bus.
CAN termination must be evaluated across the complete network rather than selected locally in isolation. The TLE7250G supports 1 Mbps communication, but achievable bus length and topology also depend on transceiver timing, wiring, stubs, termination, and electromagnetic environment. Validate dominant and recessive waveforms, fault recovery, and mixed-supply shutdown at the intended data rate before production release.
