MPN： TLE72593LEXUMA1 ✓ 啟用中TLE72593LEXUMA1 概覽
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.

典型應用
TLE72593LEXUMA1 適用於 6 應用s: Door Control Module, Seat Control Module, Climate Control Panel, Window and Mirror Switch Network, Ambient Lighting Controller, Body Control Sub-Network Node.
Door Control Module
The TLE72593LEXUMA1 fits a LIN-connected door module because it separates physical bus signaling from the protocol controller and supports conventional LIN rates from 2.4 kbps to 20 kbps. Place the transceiver at the connector-side interface and route LIN to the main PCB. Its 5.5 V to 27 V operating supply and -40°C to +150°C range suit automotive environments. The design must include the manufacturer's recommended bus interface, protection, and decoupling network. Wake-up support lets the node respond to remote bus traffic, while the INH output can assist in coordinating external power-management circuitry.
推薦
Seat Control Module
A seat-control slave module can use the TLE72593LEXUMA1 to communicate with a central body controller over a low-cost single-wire LIN network. The transceiver's 2.4 kbps to 20 kbps operating range accommodates standard LIN command and diagnostic traffic without placing physical-layer duties on the main microcontroller. Its integrated wake-up capability supports sleep-mode operation in parked vehicles, and Sleep-mode quiescent current is typically below 8 microamperes. Board layout should minimize the LIN trace between the transceiver and connector while maintaining the required protection and termination components.
推薦
Climate Control Panel
The TLE72593LEXUMA1 is appropriate for a climate-control user interface that receives button and status information through a LIN subnet. Its physical-layer transceiver works alongside a LIN protocol controller, allowing controller firmware to manage addressing, frames, diagnostics, and timing. The device supports rates through 20 kbps, which are suitable for typical control messages. Automotive supply compatibility, integrated wake-up, and the INH output broaden its usefulness in modules that must reduce standby consumption or coordinate an external regulator. Follow the manufacturer's reference circuit for ESD protection, supply filtering, bus termination, and exposed-pad thermal construction.
推薦
Window and Mirror Switch Network
A distributed switch network can connect window, mirror, and door controls to a body controller through LIN. The TLE72593LEXUMA1 handles the physical single-wire bus interface while the protocol controller manages commands and diagnostic responses. Its low Sleep-mode current of typically less than 8 microamperes is valuable when the vehicle remains inactive, and remote bus wake-up allows the node to become active when another module initiates communication. The implementation should preserve the recommended bus-protection network and use a short, controlled LIN route to reduce coupling into adjacent electronics.
推薦
Ambient Lighting Controller
The TLE72593LEXUMA1 can serve as the physical interface in an ambient-lighting slave controller operating on a LIN subnetwork. The controller handles command interpretation and LED behavior while the transceiver handles bus-level communication, wake detection, and protection. The 5.5 V to 27 V operating range supports connection to qualified automotive power rails, and the INH output can coordinate an external regulator when the module needs controlled power states. Because LED drivers can introduce switching noise, keep the LIN trace separated from high-current LED paths and follow the manufacturer's reference grounding and decoupling layout.
推薦
Body Control Sub-Network Node
The TLE72593LEXUMA1 is suitable for a compact body-control node that interfaces one or more distributed accessories to a LIN master. Its standardized 2.4 kbps to 20 kbps range supports conventional LIN communication, while integrated wake-up reduces the need for an always-active node. The device also offers Sleep-mode operation with typically less than 8 microamperes of quiescent current and an INH output for coordinating external circuitry. In a densely populated body controller, place the transceiver near the LIN connector, use a continuous ground reference, and retain the manufacturer's prescribed exposed-pad via pattern.

設計說明
Route the LIN connection from the transceiver to the connector as a short, controlled trace and keep it away from switching-converter paths, display flex cables, and high-current motor or LED routes. Use the manufacturer's ground and exposed-pad construction so the device has a low-impedance return path. Check that the external protection network and bus termination match the recommended application circuit; incorrect termination or excessive protection capacitance can distort LIN waveforms and reduce communication margin.
Use the manufacturer's recommended supply-decoupling arrangement and verify that the module's 5.5 V to 27 V supply path includes the required automotive transient protection. Decoupling capacitance, ceramic voltage rating, and placement should follow the reference design. Also assess the voltage drop across the supply path at the highest local load. The INH output must not be assumed to carry the current required by a regulator or load; it is a control signal intended for compatible external circuitry.
Do not infer pin functions from the package shape alone. The PG-TSON-8-1 device includes an exposed pad that is not an interchangeable signal pin, and the exact LIN, enable, wake, ground, and INH assignments must be taken from the TLE7259-3 pin table. Likewise, a TLE7259-3-family variant is a candidate only after checking enable polarity, wake timing, fault behavior, temperature grade, and the exact manufacturer order code against the existing schematic.
Estimated: the exposed-pad thermal resistance and allowable dissipation depend on the board's copper area, via pattern, airflow, and ambient temperature, none of which are specified for a finished module. Use the manufacturer's exposed-pad land pattern and thermal-via recommendation, provide a continuous ground plane, and validate junction temperature under the highest expected supply and bus activity. This estimation method avoids treating a generic package thermal rating as a guaranteed operating condition for a specific PCB.
