TLE7268LCXUMA1 - Dual 20 kbps LIN Transceiver | Infineon
MPN: TLE7268LCXUMA1 ✓ فعالTLE7268LCXUMA1 جائزہ
A LIN transceiver is an interface integrated circuit that connects a microcontroller or body-controller module to a single-wire automotive network bus. In the broader hierarchy, a LIN transceiver is a wired-network transceiver, an interface IC, and ultimately a semiconductor. It converts controller-level transmit and receive signals into the voltage levels required by LIN buses and provides bus protection, fault detection, sleep behavior, and wake-up functions needed in distributed vehicle electronics.
The TLE7268LCXUMA1 combines two independent LIN transceivers in one device. Each channel supports communication at up to 20 kbps and operates with 3.3 V or 5 V digital I/O levels. Its sleep mode reduces standby consumption, while wake-up capability allows a node to respond to bus activity. Very low BUSx leakage is valuable when multiple modules share a vehicle network because it reduces unintended loading and helps preserve the integrity of bus communication.
The device is compliant with ISO 17987-4, LIN Specification 2.2 A, and SAE J2602. These standards are specifically identified in the manufacturer datasheet for the TLE7268 family. The PG-TSON-14-3 package supports compact automotive circuit-board layouts and includes lead-tip inspection support according to the supplied component references, enabling automated optical inspection during production. Detailed electrical limits, pin names, ESD ratings, temperature limits, and timing values are not present in the verified excerpts and therefore remain marked as data needed rather than being inferred.
Typical uses include body-control modules, gateways, seat and door controllers, climate-control electronics, lighting controllers, and other automotive nodes that require two LIN channels. Using two transceivers in one package can simplify board partitioning when a controller communicates with two independent LIN subnets. Designers must still account for the device's 20 kbps maximum rate, digital-interface supply compatibility, sleep and wake configuration, bus termination, external microcontroller I/O, and automotive ESD requirements.
The principal design consideration is that two LIN channels do not create two independent power-management domains. Their supply, ground, enable, and common-mode implementation must follow the complete TLE7268LC datasheet. Verify pin assignments, exposed-pad requirements, bus network topology, and automotive qualification details for the exact ordered variant before releasing a production PCB.
This product record consolidates the verified manufacturer and distributor information, package characteristics, standards coverage, technical FAQs, and selection guidance. It also clearly distinguishes documented specifications from parameters that still require confirmation, helping engineers evaluate the dual-LIN interface without relying on unverified substitute parts or fabricated electrical data.

عام استعمالات
TLE7268LCXUMA1 کے لیے موزوں ہے 6 ایپلیکیشنs: Automotive Body Control Module, Automotive Gateway, Seat and Door Control Modules, Climate Control Electronics, Vehicle Lighting Controller, Distributed Sensor and Actuator Hub.
Automotive Body Control Module
The TLE7268LCXUMA1 fits a body-control module that must communicate with two independent LIN-controlled vehicle subsystems. Its two independent transceivers support rates up to 20 kbps, while 3.3 V and 5 V digital I/O compatibility allows integration with controller logic operating in either voltage domain. The transmitter timeout reduces the risk that a continuously low TxD signal will block the corresponding BUSx line. Sleep-mode operation and wake-up capability help the module manage standby consumption in a parked vehicle, while low BUSx leakage is useful when many nodes share the network.

Automotive Gateway
The TLE7268LCXUMA1 is appropriate for a gateway that links two LIN domains to a controller or higher-level vehicle network. Each of its two independent LIN channels can operate at up to 20 kbps, allowing the gateway to handle separate subnets without using two discrete transceiver packages. ISO 17987-4, LIN Specification 2.2 A, and SAE J2602 compliance provide automotive interface requirements cited by Infineon. The compact PG-TSON-14-3 package supports space-conscious board layouts, but the design must follow the datasheet's exact supply, exposed-pad, fault-protection, and bus-connection requirements.

Seat and Door Control Modules
Seat, door, and access-control modules commonly use LIN networks to connect distributed actuators and sensors. The TLE7268LCXUMA1 provides two independent LIN interfaces in one device, which can simplify wiring and board partitioning when the module must reach two separate bus nodes. Its 20 kbps maximum rate matches the stated LIN capability of the family, and 3.3 V or 5 V digital I/O levels support common automotive-controller interfaces. Low sleep current is beneficial for parked-vehicle operation, while wake-up capability allows a node to become active when supported bus activity is detected.

Climate Control Electronics
The TLE7268LCXUMA1 can serve climate-control electronics that communicate with two LIN-connected subassemblies, such as a thermal-management actuator and a sensor or control module. Two independent LIN transceivers provide separate bus connections while limiting the component count compared with two single-channel devices. Communication is supported at up to 20 kbps per channel, and the device supports 3.3 V and 5 V controller-side I/O levels. The transmitter timeout helps prevent a continuously low TxD condition from indefinitely blocking a bus, although module-specific diagnostic and fail-safe behavior must be validated against the complete application requirements.

Vehicle Lighting Controller
A vehicle lighting controller can use the TLE7268LCXUMA1 when it must communicate with two independent LIN lighting nodes. The family supports up to 20 kbps and compliance with ISO 17987-4, LIN Specification 2.2 A, and SAE J2602, providing documented automotive-network compatibility. Very low BUSx leakage is advantageous in a shared network because it minimizes unwanted loading when other modules are present. Sleep and wake behavior supports low-power parked operation, while the two-channel PG-TSON-14-3 package can reduce board partitioning compared with separate single-channel transceivers, subject to exact pin and layout verification.

Distributed Sensor and Actuator Hub
The TLE7268LCXUMA1 fits a distributed sensor or actuator hub that terminates two LIN branches used by remote automotive modules. Each independent channel offers communication up to 20 kbps, while compatibility with 3.3 V and 5 V digital I/O gives designers flexibility in controller-logic integration. The sleep-mode current and wake-up capability support duty-cycled operation, and the transmitter timeout provides a defined response when TxDx remains low because of a controller or board fault. For production use, engineers must additionally verify bus capacitance, termination strategy, protection components, and all timing and fault limits from the full manufacturer datasheet.

ڈیزائن نوٹس
Do not assign TLE7268LCXUMA1 pin functions from the package drawing alone. The verified excerpts identify a PG-TSON-14-3 device but do not provide the complete numbered pin table, exposed-pad connection, or test conditions. Download the official Infineon TLE7268 datasheet and verify BUSx, TxDx, RxDx, supply, ground, enable, and power-reset connections. Also confirm the exact ordering-code suffix before releasing library symbols or PCB land patterns.
Plan the regulator and grounding network for both LIN channels using the complete datasheet limits. The verified excerpt establishes 3.3 V and 5 V digital I/O compatibility, but it does not provide the VCC operating range, quiescent current, sleep current, or exposed-pad dissipation. Verify those values, maintain the required local decoupling, and use a low-impedance ground strategy for both transceivers so return currents do not disturb the controller-facing logic or LIN bus references.
Place each LIN BUSx connection and its protection network close to the corresponding transceiver pins. Keep the two channels physically distinct where practical, route them away from sensitive controller signals, and follow the manufacturer's recommended layout and protection-component arrangement. The lead-tip inspection feature supports automated optical inspection, but it does not replace good solderability design; confirm land geometry, paste volume, reflow profile, and exposed-pad assembly requirements against the package documentation.
