TLE7269GXUMA1 - 20 kBaud Dual LIN Transceiver | Infineon
부품 번호: TLE7269GXUMA1 ✓ 활성TLE7269GXUMA1 개요
A LIN transceiver is an automotive interface IC that converts logic-level controller signals into the physical LIN bus waveform and receives bus data for recovery by a microcontroller or LIN-capable communication controller. LIN belongs to the vehicle network hierarchy rather than high-speed Ethernet or CAN networks. It provides a cost-effective single-wire bus for distributed body, comfort, seat, door, lighting, and sensor modules.
The TLE7269GXUMA1 provides two independent stand-alone LIN transceivers with a maximum transmission rate of 20 kBaud. Its LIN 2.0 and LIN 2.1 compliance, together with SAE J2602 compliance, makes it appropriate for modern vehicle electrical systems. The device is pin compatible with single LIN transceivers such as the TLE7259-2GE and TLE7259-GU, allowing integration of two LIN channels while preserving familiar transceiver connections.
Electrical robustness is a major design consideration for vehicle wiring harnesses. The TLE7269GXUMA1 provides very high ESD robustness rated at 8 kV according to IEC 61000-4-2. This protection helps improve tolerance of direct and indirect ESD events encountered during vehicle assembly, servicing, and operation. The device is also optimized for low electromagnetic emission and high immunity against electromagnetic interference, supporting stable operation in electrically noisy automotive environments.
Typical uses include body-control modules, door and seat controllers, climate-control electronics, lighting controllers, gateway modules, and other ECUs that require two LIN ports. Each transceiver can interface a local microcontroller with a physical LIN network bus, while low electromagnetic emission helps reduce interference with nearby sensitive electronics.
Designers should verify transceiver enable, sleep, wake-up, supply-voltage, and bus-line details against the manufacturer datasheet before layout. The automotive 14-terminal DSO package also requires adequate board area, pin-1 orientation, and production-quality assembly controls. Access to the detailed pin table was not present in the supplied source excerpts, so pin-level assignment should not be inferred from the package drawing alone.
This product page consolidates verified LIN capabilities, package information, ESD rating, compliance claims, distributor availability, and design considerations. It also distinguishes confirmed drop-in alternatives from unverified substitutes so engineers can make evidence-based sourcing and design decisions without relying on assumptions.

일반적인 애플리케이션
TLE7269GXUMA1 적합 용도: 6 애플리케이션s: Automotive Body Control Module, Door and Seat Control Module, Climate Control Electronics, Lighting Control Unit, Automotive Gateway Module, Industrial LIN Sensor Node.
Automotive Body Control Module
The TLE7269GXUMA1 fits an automotive body-control module that connects distributed door, seat, lighting, and climate-control loads to a LIN-capable microcontroller. Its two stand-alone transceivers support communication at up to 20 kBaud, while support for LIN 2.0, LIN 2.1, and SAE J2602 aligns the device with established vehicle-network requirements. The 8 kV IEC 61000-4-2 ESD rating is valuable because body modules frequently connect to wiring harnesses exposed to electrostatic discharge. Low-EME optimization also helps reduce coupling into neighboring controller electronics, although system-level EMC validation remains necessary.
추천
Door and Seat Control Module
The TLE7269GXUMA1 is suitable for a door or seat controller that must communicate with remote LIN nodes such as switches, motors, sensors, and latches. Combining two LIN transceivers in a single PG-DSO-14-24 package can simplify multi-channel implementations while retaining a 20 kBaud maximum data rate. Its optimized low electromagnetic emission is beneficial in compact modules where motor drivers, relays, and sensor inputs share the enclosure. Automotive temperature grading and 8 kV ESD robustness support use in harsh vehicle environments, subject to confirmation of detailed operating limits from the manufacturer datasheet.
추천
Climate Control Electronics
The TLE7269GXUMA1 can serve climate-control electronics that monitor distributed fan, flap, temperature, and control-panel nodes over LIN. Two integrated stand-alone channels allow one controller to manage two bus segments without using two separate transceiver packages. The device’s 20 kBaud rate is appropriate for LIN command and diagnostic traffic, and its high EMI-immunity optimization supports operation near switching power stages, relays, and fan electronics. Engineers should still budget appropriately for reverse-battery, load-dump, transient, and grounding conditions at the vehicle power-interface stage.
추천
Lighting Control Unit
The TLE7269GXUMA1 fits an exterior or interior lighting control unit that communicates with remote lamp nodes, ambient-light sensors, or switch modules through LIN. A 20 kBaud dual-transceiver arrangement supports two independent LIN connections while limiting the component count compared with two discrete single-channel devices. The low-EME characteristic is especially useful where LED drivers and other fast-switching circuitry share a small PCB. The verified 8 kV IEC 61000-4-2 ESD rating adds interface robustness for harness-connected nodes, but the complete vehicle transient and CISPR 25 validation must be performed at the product level.
추천
Automotive Gateway Module
The TLE7269GXUMA1 is appropriate for a gateway or body-electronics module that bridges slower LIN subnets to a faster vehicle backbone. Its two stand-alone LIN channels can terminate separate buses while a host processor or communication controller handles packet routing and diagnostics. At up to 20 kBaud, the device matches typical LIN control traffic, and LIN 2.0, LIN 2.1, and SAE J2602 support provides clear protocol compatibility. Optimized low electromagnetic emission and high immunity are beneficial in a gateway that also contains Ethernet, CAN, or high-speed processor circuitry, subject to system EMC testing.
추천
Industrial LIN Sensor Node
The TLE7269GXUMA1 can be used in a robust LIN sensor node where two low-speed sensor buses or actuator links are required. Its LIN 1.3, LIN 2.0, and LIN 2.1 support permits interoperability with common LIN devices, while the 8 kV ESD rating improves robustness against electrostatic discharge on externally routed cables. Low-EME operation helps limit disturbance to nearby analog or digital sensor circuitry, and sleep current below 10 mA supports reduced-consumption designs. The automotive temperature grade should be checked against the industrial environment’s full temperature range before deployment.

설계 노트
Use the manufacturer PG-DSO-14-24 land pattern and verify pin-1 orientation against the official package drawing before fabrication. Keep each LIN transceiver connection close to its assigned pins and route the bus conductor away from clocks, switching nodes, and sensitive analog inputs. The verified source confirms the package family but does not provide the full pin table, so the schematic and PCB should not be released solely from this product page.
The TLE7269GXUMA1 is optimized for low electromagnetic emission and high immunity, but those device characteristics do not replace vehicle-level EMC testing. Use a controlled LIN bus topology, minimize stub lengths, place protection components near connector entries, and maintain the separation recommended by the manufacturer application guidance. Correlate conducted and radiated emissions with transient-immunity results before production release.
Do not treat the stated pin compatibility with TLE7259-2GE and TLE7259-GU as proof that those single-channel devices are drop-in replacements for this dual-channel package. Confirm the number of LIN buses, logic levels, enable and sleep behavior, supply requirements, bus-line topology, and package footprint. Also verify that the eight-kilovolt IEC 61000-4-2 ESD rating applies to the exact protection configuration implemented in the final design.
