TLE72593LEXUMA1

TLE72593LEXUMA1 - 20kbps LIN Transceiver | Infineon Technologies

The Infineon Technologies TLE72593LEXUMA1 is a LIN bus transceiver for in-vehicle communication systems, supporting data rates from 2.4 kbps to 20 kbps in an 8-pin PG-TSON-8-1 package. It operates from a 5.5 V to 27 V supply and includes a LIN bus driver, receiver, integrated wake-up capability, and protection features for robust connection to a Local Interconnect Network. A LIN transceiver, also called a LIN interface or physical-layer transceiver, is an interface IC that converts logic-level signals from a LIN protocol controller into physical bus signals and converts incoming bus activity back into controller-compatible signals. Within the automotive electronics hierarchy, a LIN transceiver is a communications transceiver, an interface IC, and a semiconductor used in vehicle body and comfort electronics. The TLE7259-3 supports LIN standards and data rates from 2.4 kbps to 20 kbps. Its integrated wake-up functions allow the network node to detect remote LIN bus traffic or a local wake-up signal. The INH output provides an additional control signal for external circuitry such as a voltage regulator. According to the manufacturer information, Sleep-mode quiescent current is typically below 8 microamperes, while the BUS input uses very low leakage current. The device functions as the physical bus driver between a LIN protocol controller and the LIN wiring harness. This division of responsibility keeps waveform generation, bus-level detection, wake-up handling, and fault protection within a dedicated interface IC. The resulting architecture is suitable for distributed vehicle networks in which multiple low-cost nodes exchange small control messages over a single-wire bus. Typical uses include door modules, seat controls, window and mirror switches, climate-control panels, body-control modules, ambient lighting controls, and other LIN sub-networks. Its wide operating supply range supports automotive electrical environments, while the 20 kbps limit fits conventional LIN communication rather than high-speed automotive Ethernet or other high-bandwidth vehicle networks. For implementation, use the manufacturer pin-description and application information to assign LIN, supply, ground, enable, wake-up, and INH functions. Place the transceiver and its supporting components close to the connector or bus branch, maintain the required input and output capacitors, and follow the recommended bus termination and layout guidance to reduce radiated noise and susceptibility to interference. This product overview combines the device's verified operating limits and automotive features with practical guidance on LIN integration, low-power operation, protection, and design trade-offs. It is intended to help engineers evaluate bus compatibility, package constraints, wake-up behavior, and replacement decisions before committing a PCB design.

TLE7259G

TLE7259G - 20 kBaud LIN Transceiver | Infineon | Automotive

The Infineon Technologies TLE7259G is an automotive LIN transceiver supporting data rates from 2.4 kBaud to 20 kBaud, with a specified 3.5 V to 5.5 V operating range, integrated wake-up functionality, and integrated protection features. It is packaged in an 8-pin SOIC and is intended for Local Interconnect Network nodes in in-vehicle communication systems. The verified source identifies the TLE7259G as a LIN transceiver, while several detailed electrical limits and pin assignments remain unavailable in the supplied data. A LIN transceiver is an interface IC that connects a microcontroller UART to a LIN bus. LIN, or Local Interconnect Network, is a low-cost, single-wire vehicle network commonly used for sensors, actuators, body electronics, and comfort systems. The transceiver translates logic-level signals between the host controller and the LIN physical bus, while wake-up and protection functions support reliable operation in electrically harsh environments. Its 20 kBaud maximum rate matches the source description for in-vehicle LIN networks. The key verified characteristics are the 2.4 kBaud-to-20 kBaud data-rate range, 3.5 V-to-5.5 V supply range, integrated wake-up, integrated protection, and 8-pin SOIC construction. These features make the device applicable to distributed vehicle nodes where a host MCU requires a standardized LIN physical layer. The source does not provide verified values for transceiver mode, sleep current, bus thresholds, propagation delay, ESD rating, or absolute maximum ratings, so those parameters are not inferred here. TLE7259G is most relevant to body and comfort modules, sensor interfaces, actuator controllers, door and window modules, climate-control systems, and other LIN subnets. The host microcontroller handles LIN frame generation and protocol timing; the transceiver supplies the physical-layer connection. Designers must confirm the complete LIN electrical specification, pinout, external components, supply sequencing, and protection requirements against the manufacturer datasheet before production release. For PCB implementation, place the transceiver close to the LIN bus connection and route the single-wire bus away from sensitive analog and high-speed digital signals. The LIN bus requires an appropriate pull-up arrangement and protection strategy; exact resistor and protection values should follow the verified datasheet and system-level EMC requirements. Keep the supply and ground return paths short, and verify the device's wake-up behavior in the intended low-power architecture. This page combines the verified TLE7259G source descriptions, pricing references, package information, and cross-reference findings with engineering selection context. The supplied data does not establish enough verified information to populate every electrical specification, complete pinout, lifecycle classification, or qualified drop-in alternative without risking an inaccurate replacement recommendation.

TLE7259GNT - 20kBd LIN Transceiver, P-DSO-8 | Infineon

Infineon Technologies TLE7259GNT is an automotive-grade LIN bus transceiver operating at 20 kBd in an 8-pin P-DSO-8 surface-mount package. Verified distributor data identifies a 1/1 transceiver arrangement, full LIN-bus operation, an 8-terminal gull-wing package, and an operating-temperature range of -40°C to 150°C. The device belongs to the LIN interface-transceiver category and converts between a host controller's logic-level UART signals and the physical LIN network. Its principal electrical values, including supply voltage limits, receiver hysteresis, output-driver details, and sleep or wake behavior, were not included in the supplied verified records and therefore require confirmation from the manufacturer datasheet before design release. The public parts database labels TLE7259GNT obsolete or end-of-life, although distributor listings remain available. Engineers should treat lifecycle status, stock, and sourcing conditions as time-sensitive rather than assuming broad future availability. TLE7259GNT is associated with automotive LIN subnets, body electronics, climate controls, seat modules, door modules, lighting controllers, and sensor gateways where a standardized low-speed serial bus connects distributed nodes. Its 20 kBd LIN rate is suitable for control and status traffic rather than high-bandwidth payloads. The package keeps the physical implementation compact, but successful deployment still depends on correct transceiver pin mapping, bus termination, reference-ground handling, ESD protection, decoupling, and compliance with the LIN network requirements used by the vehicle platform. This page summarizes verified distributor and database records, available sourcing information, documented package and protocol details, and the unresolved datasheet parameters that must be checked before substitution or PCB release.

TLE7259GT

TLE7259GT - 20 kBd LIN Transceiver | Infineon | Automotive

The Infineon TLE7259GT is a half-duplex LIN bus transceiver with one transmitter and one receiver, a 7 V to 27 V supply range, and a maximum transmission rate of 20 kBaud. The device is packaged for surface-mount assembly in an 8-pin DSO/SOIC-style package and is supplied in tape-and-reel packaging. It complies with LIN specification versions 1.3, 2.0, and 2.1, while also supporting the ISO 9141 K-line function. A LIN transceiver is an interface IC that connects a host microcontroller to a low-cost, single-wire automotive communication bus. LIN belongs to the broader CAN and automotive-network hierarchy: a CAN bus is a high-speed, multi-node network, while LIN uses a slower serial protocol optimized for cost-sensitive distributed vehicle subsystems. The TLE7259GT converts logic-level requests from a controller into LIN-bus signals and converts received bus levels into logic signals for the controller. The TLE7259GT supports transmission rates through 20 kBaud and includes LIN specification compatibility for versions 1.3, 2.0, and 2.1. Its 7 V to 27 V operating supply range accommodates vehicle battery environments. Additional cited features include K-line support under ISO 9141, very high ESD robustness, and very low electromagnetic emission. These characteristics make the device relevant to LIN nodes requiring protocol compatibility and strong protection against conducted or capacitive bus disturbances. Technically, the device combines a bus-side transmitter and receiver with the interface needed for an embedded host. A microcontroller can control bus dominance, monitor received frames, detect communication errors, and implement LIN scheduling. Because LIN commonly operates from a vehicle supply, the 27 V maximum operating voltage provides additional margin relative to 5 V transceiver packages, although the final design must still account for load dump and transient requirements at the wiring interface. Typical applications include body-control modules, door and seat controllers, climate-control panels, lighting controllers, automotive gateways, and other distributed electrical subsystems. The K-line function broadens its utility in diagnostic or legacy vehicle interfaces, while the 20 kBaud rate matches common LIN physical-layer implementations. Designers should verify bus termination, supply decoupling, transceiver sleep behavior, and protection requirements against the manufacturer datasheet before layout release. The LIN bus wiring is sensitive to ground offsets, capacitance, reflections, and ESD events, so PCB placement and vehicle harness design remain as important as the nominal IC specification. This product page consolidates verified specifications, sourcing context, application guidance, and strict drop-in replacement criteria. Where the supplied web evidence does not establish a complete pin map, pricing schedule, or lifecycle designation, those details remain explicitly unverified rather than being inferred.

The TLE7263E consolidates several discrete automotive functions into one IC, reducing PCB area and the number of external network-interface components. Its 150 mA, 5 V regulator capability is suitable for low-power automotive loads, although it is not intended to power loads whose current exceeds that rating. The exposed-pad package also requires attention to PCB thermal design and copper placement. Typical uses include automotive body-control modules, door and seat controllers, climate-control electronics, lighting-control units, LIN-connected actuators, gateways combining LIN and CAN, and other low-voltage vehicle electronics. Designers should verify transceiver limits, regulator startup behavior, pin electrical limits, and watchdog operation directly against the manufacturer datasheet before production release. For layout, place the device close to protected vehicle-power entry, route high-current switched paths with adequate copper, and keep sensitive CAN and LIN nodes compact and isolated from switching edges. Confirm startup sequencing, diagnostic behavior, watchdog timing, and sleep-mode current in the target ECU environment. This page combines verified manufacturer-linked specifications, distributor package information, application guidance, and replacement-policy checks. It does not claim an unqualified drop-in alternative because the supplied cross-reference results did not verify five pin-compatible parts.

It is designed for LIN vehicle-network nodes requiring ISO 17987-4, LIN Specification 2.2 A, and SAE J2602 compliance. The integrated pair of transceivers supports 3.3 V and 5 V digital I/O levels, low sleep-mode current consumption, wake-up capability, and very low leakage on the BUSx pins. 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.

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.

The device provides the physical-layer interface between the host controller and each LIN bus. Its digital transmit and receive pins connect to a microcontroller, while BUS1 and BUS2 connect to the LIN network. The independent-channel architecture allows one transceiver package to serve two LIN networks, reducing component count and PCB area compared with two separate single-channel LIN transceivers. External implementation details, including bus termination, wake-up wiring, and logic pull-ups, must follow the manufacturer datasheet. Typical uses include body-control modules, automotive gateways, seat and door modules, climate-control units, sensor nodes, and other ECUs connected by LIN sub-buses. Because the TLE7268SKXUMA1 supports two channels, it is especially useful where one ECU must interface with two separate LIN networks or where a gateway bridges multiple vehicle subsystems. For PCB implementation, preserve the package-specific land pattern, place the transceiver close to the LIN connector or bus routing, and keep BUS traces away from sensitive high-speed signals. Decoupling and signal-integrity values are not specified in the supplied verified excerpts, so component selection and layout must be completed against the complete manufacturer datasheet.

TLE7729TXUMA1

TLE7729TXUMA1 - 4-Channel Airbag Receiver | Infineon

The Infineon Technologies TLE7729TXUMA1 is a four-channel airbag satellite receiver IC using the company’s SatRIC serial interface architecture. It is designed for automotive occupant-protection systems in which remote satellite sensors report acceleration and crash-relevant measurements to a central airbag control module. The device is offered in a 28-pin PG-TSSOP surface-mount package and is supplied in tape-and-reel packaging. An interface IC is an integrated circuit that connects sensors, controllers, and other system blocks using standardized electrical signaling. Within the automotive electronics hierarchy, the TLE7729TXUMA1 belongs to the specialized interface IC category rather than a general-purpose communications transceiver. Its defining role is to receive information from multiple remote sensing nodes and forward it to the vehicle safety controller over a serial interface, reducing the number of separate wiring connections required by a distributed restraint system. According to the available TLE7729 documentation, the principal identified functions are four-channel satellite reception, SatRIC operation, and a serial interface for automotive airbag systems. The automotive qualification designation and specialized SatRIC architecture make the IC suitable only where the surrounding sensing, bus, and restraint-control architecture is compatible with Infineon’s system. It should not be treated as a general-purpose UART, SPI, or CAN transceiver because the verified sources describe a dedicated satellite-receiver application. The verified component information identifies the package as PG-TSSOP-28, also described by distributors as a 28-pin TSSOP. Tape-and-reel ordering is indicated by the TXUMA1 ordering code and by distributor listings that identify the part as 28TSSOP T/R. Because the retrieved sources do not expose individual terminal names or a complete pin-assignment table, the package diagram is identified separately from the electrical pin map. Typical uses include distributed airbag satellite sensors, remote acceleration-sensing modules in vehicle restraint systems, and central airbag control units that collect crash data from several remote sensor locations. The four-channel architecture supports multi-axis sensing systems by consolidating several satellite signals behind a dedicated serial receiver. The critical design constraint is system-level interoperability. A PCB redesign should preserve the Infineon-defined SatRIC physical interface, power distribution, reference connections, and communication timing because no verified evidence in the supplied data confirms that an unrelated generic interface IC is pin-to-pin compatible. Vehicle-level EMC behavior, diagnostic coverage, and air-quality or functional-safety conclusions should be validated against the complete manufacturer datasheet and the deployment platform rather than inferred from distributor summaries.

The Infineon TLE8250G is a high-speed CAN transceiver with one transmitter and one receiver, data rates up to 1 Mbit/s, and ISO 11898-2 compliance in an eight-pin PG-DSO-8 surface-mount package. It serves as the physical-layer interface between a CAN protocol controller and a two-wire differential CAN bus. According to the Infineon product page and manufacturer datasheet, the device is designed for automotive and industrial networks, with low electromagnetic emissions and emissions-related interference, high electromagnetic immunity, and robust ESD protection. A CAN transceiver is a network interface IC within the broader communications-semiconductor hierarchy. It converts logic-level TXD and RXD signals into the differential CANH and CANL bus signals, then converts received bus levels back into a controller-compatible RXD signal. High-speed CAN is a two-wire differential network designed for robust, priority-based communication between electronic control units, where common-mode rejection and disturbance tolerance are central to reliable operation. The TLE8250G combines a 1 Mbit/s-capable CAN driver with a receiver interface and bus protection functions. Its symmetric CANH and CANL behavior supports low EMI in applications where electronic modules must coexist on a shared harness. The device supports partially supplied networks, an important characteristic for automotive systems where some nodes can be unpowered while others remain active. In power-down mode, receiver input resistors are switched off so the transceiver input becomes highly resistive, reducing unwanted loading of an inactive bus. Infineon Smart Power Technology combines bipolar and CMOS control circuitry with DMOS power devices on one monolithic circuit. The manufacturer describes this technology as supporting high ESD robustness and high electromagnetic immunity. The TLE8250G and its Smart Power Technology are stated to be AEC qualified. The transceiver also meets or exceeds ISO 11898-2 requirements and is offered in a RoHS-compliant PG-DSO-8 package, making it appropriate for electronic control units, body modules, gateways, sensors, and industrial automation interfaces. Use the TLE8250G when the PCB already expects an eight-pin PG-DSO-8 CAN interface and the bus operates at or below 1 Mbit/s. Designers should confirm the transceiver I/O voltage against their controller, preserve the CAN bus termination network, and follow the manufacturer’s layout guidance to minimize radiated emissions. Because only verified electrical limits, supply ranges, temperature ranges, and pin-level details are not included in the supplied search data, those values require confirmation in the manufacturer datasheet before release to production. The TLE8250G is also fully pin- and function-compatible with its Infineon predecessor, the TLE6250G, according to the verified manufacturer documentation. This predecessor relationship provides a documented upgrade path, but design reviews should still compare operating voltages, timing, transient immunity, and lifecycle requirements for the exact production variant. This page synthesizes manufacturer specifications, compatibility information, application guidance, and sourcing references that are not presented together on a distributor search page.
