TLE7269G - Dual LIN Transceiver, 20 kBaud | Infineon
MPN： TLE7269G ✓ 啟用中TLE7269G 概覽
A LIN transceiver, also called a LIN bus interface, belongs to the vehicle-network interface IC hierarchy and connects a microcontroller or cluster ECU to a low-speed serial network. It converts logic-level transmit and receive signals into physical LIN bus signals, while recovering incoming data for the host controller. The TLE7269G combines two LIN channels in one package, reducing board area where multiple vehicle subnets or redundant communication links are required.
Key features include dual-channel operation, LIN 2.1 compliance, integrated wake-up capability, protection features, low EMI, and a sleep-mode current below 10 mA. Its data-rate range of 2.4 kBaud to 20 kBaud matches the operating range cited in the manufacturer datasheet. The very low leakage current on the bus pins also supports partially supplied LIN networks, helping nodes that remain unpowered avoid loading the active network.
The TLE7269G is based on Infineon Smart Power Technology SPT, according to the manufacturer datasheet. This process combines digital control functions with automotive-grade power and interface robustness. The manufacturer specifically highlights excellent ESD robustness and high electromagnetic immunity, both important in vehicle electrical environments where cable-borne transients and radio-frequency coupling can disrupt low-speed communication.
Typical uses include body-control modules, door and seat controllers, climate-control panels, lighting controllers, seat and door modules, and other ECUs connected through LIN subnets. The dual-channel configuration is particularly useful when an ECU needs two independent LIN endpoints or participates in more than one vehicle network segment.
When designing around the TLE7269G, preserve the recommended external resistor, capacitor, and bus-termination arrangements from the manufacturer datasheet. Keep the LIN bus route away from sensitive analog signals and provide the required pull-up and wake-up components to avoid excessive bus loading. The low sleep current and bus leakage support low-power designs, but functional sleep and wake behavior must still be verified against the complete network topology.
This page combines verified manufacturer and distributor facts with a focused comparison of the most relevant substitute candidates, application guidance, and practical interface-design notes. It distinguishes published characteristics from parameters that still require direct confirmation for a specific ordering code or design revision.

典型應用
TLE7269G 適用於 7 應用s: Automotive Body Control Module, Door and Lock Control Module, Automotive Lighting Controller, Climate Control Panel Interface, Seat Control Network Interface, Automotive Sensor Gateway, In-Vehicle Network Test and Diagnostics.
Automotive Body Control Module
The TLE7269G fits body-control modules that require two LIN endpoints for distributed switches, locks, lighting, or seat functions. Its dual LIN 2.1 channels support 2.4 kBaud to 20 kBaud communication, while integrated wake-up and protection reduce the number of discrete interface functions around the ECU. The device's sleep-mode current below 10 mA and very low bus leakage also help when some network nodes remain unpowered. In implementation, connect each LIN channel to its own bus pins and external components exactly as shown in the Infineon manufacturer datasheet.
推薦
Door and Lock Control Module
A door or lock ECU can use the TLE7269G when it communicates through separate LIN subnetworks or needs dual physical interfaces. The 20 kBaud maximum data rate fits the manufacturer's stated in-vehicle LIN range, while low EMI reduces coupling into nearby electronics. Integrated wake-up allows network activity to wake the interface, and protection features address the harsh electrical environment. Because the verified sources do not provide exact voltage thresholds, pin functions, or external values, the implementation must follow the official Infineon datasheet rather than generic LIN examples.
推薦
Automotive Lighting Controller
The TLE7269G is appropriate for lighting ECUs that monitor or control multiple low-speed vehicle nodes. Its two integrated LIN transceivers can consolidate communication paths while maintaining a 2.4 kBaud-to-20 kBaud operating range. Low EMI is valuable around sensitive lighting-control electronics, and the low sleep current helps manage parked-vehicle energy use. Board designers should retain the specified pull-up arrangement, route LIN away from fast-switching power stages, and verify ground and return paths using the manufacturer application guidance.
推薦
Climate Control Panel Interface
A climate-control panel can use the TLE7269G for LIN links to HVAC nodes, buttons, sensors, or actuators distributed around the passenger compartment. The dual-channel arrangement saves board space compared with two separate single-channel transceivers, while the 20 kBaud capability supports the stated LIN range. The device's low EMI and high electromagnetic immunity are advantageous in a panel containing display, switch-scanning, and communications circuitry. Validate wake-up sensitivity and coexistence with panel-local noise sources in the final vehicle electrical environment.
推薦
Seat Control Network Interface
The TLE7269G fits seat modules that interface with adjustment motors, position sensors, or occupant-related controllers over LIN. Two channels can serve separate network segments or support a spare communication path, reducing the need for another transceiver package. Its integrated wake-up and protection are useful for a vehicle network where modules sleep between commands, while sleep-mode current below 10 mA supports low standby demand. Maintain the datasheet-specified bus termination and pull-up strategy, and confirm that the MCU supports the required LIN frame timing.
推薦
Automotive Sensor Gateway
The TLE7269G can serve as the physical interface in an ECU that gathers information from LIN-connected sensors or consolidates two LIN subnets. Supporting 2.4 kBaud to 20 kBaud covers the manufacturer's stated communication range, and integrated wake-up allows bus activity to initiate node activity. The very low leakage current on bus pins is especially useful when some sensor nodes are only partially supplied. Since the verified data does not state input thresholds, transceiver delay, or wake pulse width, engineers should use the manufacturer datasheet and validate timing in worst-case network conditions.
推薦
In-Vehicle Network Test and Diagnostics
The TLE7269G can be incorporated into diagnostic or network-node equipment intended to exercise LIN communication in an automotive environment. Its dual channels permit two bus connections without duplicating the external interface architecture, and its low EMI reduces disturbance during measurement. The 2.4 kBaud-to-20 kBaud range allows tests across the supported LIN operating region. The integrated protection and wake-up functions are useful when connecting to partially supplied networks, but the instrument must provide isolation and protection appropriate to the vehicle harness rather than relying only on the transceiver.

主要差異化特點
- Two LIN channels integrated in one package (對比MCP2004-E/SN)
- Published LIN 2.1 compliance and 20 kBaud support (對比TJA1021U/10)
- Low sleep current for vehicle standby operation (對比TJA1021U/20)
- Manufacturer-documented wake-up, protection, and bus behavior (對比MCP2004-E/SN)
設計說明
Route each LIN channel exactly as the Infineon manufacturer datasheet recommends, including its prescribed pull-up, bus-termination, and decoupling arrangement. Keep the LIN path away from switching nodes, high-current motor returns, and sensitive analog traces; maintain a continuous ground reference beneath the interface. Because the verified material does not provide complete pin names or PCB values, do not infer them from generic LIN schematics. Confirm every connection against the package-specific drawing and latest datasheet before release.
Calculate standby demand from the whole LIN node rather than the transceiver alone. The TLE7269G sleep-mode current is below 10 mA, and its bus leakage is described as very low, but the host MCU, pull-up resistors, wake-up circuitry, and external sensors can dominate the parked-system load. Measure the assembled module with every attached ECU in its expected sleep or unpowered state. This system-level check also validates that partially supplied nodes do not create false wake events or excessive bus loading.
Do not treat a cross-reference listing as proof of drop-in compatibility. The verified alternatives include single-channel MCP2004 and TJA1021 candidates, whereas the TLE7269G provides two LIN channels. A board requiring two channels may need two substitutes and a different footprint. Verify package drawing, pin names, supply range, bus thresholds, wake logic, timing, protection, and transceiver disable behavior before substitution. Also verify that software or hardware LIN timing accommodates any difference between the replacement and the original 20 kBaud dual-channel device.
The Infineon manufacturer datasheet identifies low EMI as a key optimization and highlights very high electromagnetic immunity, so preserve that performance with disciplined layout rather than adding arbitrary bus filters. Avoid long parallel runs with power or high-speed signals, minimize loop area around external bus components, and keep the return path continuous. EMI qualification still depends on harness, module enclosure, neighboring ECUs, and switching supplies, none of which are represented by the component-level datasheet.
合規資訊
The verified data identifies an automotive temperature grade and cites Infineon Smart Power Technology SPT, excellent ESD robustness, and high electromagnetic immunity. It does not explicitly state RoHS, REACH, AEC-Q100 qualification, lead-free status, halogen-free status, or conflict-minerals compliance, so those fields remain unknown.
