TLE72592GEXUMA1 - 20 kbaud LIN Transceiver | Infineon
부품 번호: TLE72592GEXUMA1 ✓ 활성TLE72592GEXUMA1 개요
A LIN transceiver is an interface IC that connects a low-cost serial bus used in vehicle body and comfort systems to a host microcontroller. Its hierarchy is LIN transceiver, automotive transceiver, interface IC, and semiconductor. The transceiver converts logic-level signals into the LIN bus waveform, receives bus data, and supports low-power wake-up behavior. This makes the device suitable for door modules, seat controls, climate controls, lighting, and other distributed automotive nodes.
The TLE72592GEXUMA1 supports LIN 1.3 and LIN 2.x communication at rates up to 20 kBaud while maintaining a 5.5 V to 27 V supply range. Its 3.3 V or 5 V receive output allows connection to microcontrollers operating at either logic level. Integrated wake-up and protection features reduce external circuitry and improve suitability for electrically demanding automotive networks.
The device combines a bus driver, receiver, and LIN-specific interface functions in one package. Its architecture is intended for unidirectional or bidirectional LIN communication in distributed vehicle systems. Compared with a general-purpose CAN or RS-232 interface, the TLE72592GEXUMA1 is designed specifically for LIN's single-wire topology, lower signaling rates, and automotive power environment.
Typical uses include LIN-controlled vehicle body electronics, ambient lighting modules, powered seat and window controllers, climate-control panels, sensor interfaces, and gateway nodes. The 8-pin SOIC-8 format also supports conventional surface-mount assembly. Because LIN transceivers operate close to motor systems, relays, and other potentially noisy loads, correct bus termination, reference-ground implementation, and PCB layout remain essential.
For a new design, verify the LIN controller voltage, wake-up polarity, transceiver mode, and bus capacitance against the manufacturer datasheet. Place the transceiver close to the LIN connector, keep the LIN route away from switching nodes and high-current paths, and use the prescribed pull-up and termination networks. The external component values and layout should follow the manufacturer's reference configuration.
This product page organizes the key automotive LIN interface facts, replacement options, comparison parameters, and practical PCB guidance. It helps engineers evaluate the TLE72592GEXUMA1 as an 8-pin, 20 kbaud LIN transceiver before beginning a new vehicle-network design.

일반적인 애플리케이션
TLE72592GEXUMA1 적합 용도: 6 애플리케이션s: Automotive LIN Body-Control Nodes, Door and Seat Control Modules, Vehicle Climate-Control Interfaces, Automotive Lighting-Control Modules, LIN Sensor and Actuator Hubs, Automotive Gateway and LIN-to-CAN Bridges.
Automotive LIN Body-Control Nodes
The TLE72592GEXUMA1 fits distributed vehicle body-control modules that exchange commands over a LIN bus. Its specified 2.4 to 20 kBaud range accommodates LIN 1.3 and LIN 2.x networks, while the 5.5 V to 27 V supply range accommodates common 12 V and 24 V vehicle environments. The 3.3 V or 5 V logic output supports host microcontrollers at either logic level. Integrated wake-up and protection functions help simplify low-power module design, although the final external pull-up, termination, and wake-up network should follow the manufacturer reference configuration.
Door and Seat Control Modules
Door locks, seat-position controls, and powered access modules commonly use LIN for economical communication between an ECU and peripheral smart actuators. The TLE72592GEXUMA1 provides a 20 kBaud maximum LIN data rate, matching the lower-speed distributed-network role, and integrated wake-up support can help reduce module standby consumption. Its 8-pin SOIC-8 package supports compact surface-mount assemblies. Engineers should account for motor-bridge transients, maintain a clean return path, and verify that the selected microcontroller can operate with the device's 3.3 V or 5 V receive output.
Vehicle Climate-Control Interfaces
Climate-control panels, blower controllers, and temperature-sensor nodes can use the TLE72592GEXUMA1 as the LIN physical interface. The 5.5 V to 27 V operating range suits vehicle power systems, and communication up to 20 kBaud is appropriate for LIN-based climate functions. A 3.3 V or 5 V logic output enables connection to either supported controller family. Because blower and fan systems can generate electrical noise, the layout should keep the transceiver and LIN trace away from motor-switching paths while following the manufacturer's reference grounding and external-component arrangement.
Automotive Lighting-Control Modules
Ambient-lighting strips, interior lamps, and exterior lighting controllers often use LIN to connect a central body ECU with distributed lamp modules. The TLE72592GEXUMA1 supports 2.4 to 20 kBaud data rates and LIN 1.3 or LIN 2.x communication, which aligns with typical low-bandwidth lighting-control networks. Its 3.3 V or 5 V output gives flexibility in host-controller selection, while wake-up integration assists low-power operation. Validate the transceiver and bus pull-up network against the module's standby-current target and test operation with the vehicle's LED-driver switching circuitry.
LIN Sensor and Actuator Hubs
The TLE72592GEXUMA1 can serve as the bus interface in hubs that connect sensors, switches, or actuators to a vehicle LIN segment. Its integrated protection functions are useful in distributed nodes, while the 20 kBaud maximum rate covers standard LIN communication requirements. The device's 8-pin package keeps the interface compact enough for space-constrained modules. Placement near the connector and LIN bus reduces susceptibility to radiated and conducted vehicle noise, while a stable reference-ground connection prevents bus-level shifts that could cause communication errors or unintended wake-up behavior.
Automotive Gateway and LIN-to-CAN Bridges
A gateway or protocol-conversion module can use the TLE72592GEXUMA1 as the LIN-side physical interface when another bus handles higher-bandwidth traffic. The 2.4 to 20 kBaud range matches standard LIN traffic, and the 3.3 V or 5 V logic output allows the LIN controller side to operate with suitable digital logic. The wide 5.5 V to 27 V supply range supports vehicle power systems. In a mixed-protocol design, keep switching regulators and high-speed interfaces physically separated from the LIN connector and transceiver, and validate timing margins across the complete automotive bus network.

설계 노트
Place the TLE72592GEXUMA1 close to the LIN connector and route the LIN conductor as a short, controlled-impedance path. Keep the transceiver, bus pull-up, and connector on the same side of the PCB where practical. Provide a direct return path to the vehicle reference ground and avoid sharing narrow copper sections with high-current motor or relay returns. These measures reduce susceptibility to common-mode voltage shifts, radiated coupling, and unintended wake-up events.
Use the manufacturer application circuit and pin-description table as the authority for the LIN, LIN bus, RxD, supply, ground, enable, and wake-up connections. The TLE7259-2GE requires a pull-up resistor at RxD, so do not copy a circuit intended for a dual-supply transceiver without checking that difference. Confirm the SOIC-8 orientation on the assembly drawing and preserve clearance around exposed or adjacent bus pins during automated optical inspection.
Do not select a replacement from the base family name alone. The TLE72592GEXUMA1 and TLE7269G both use 8-pin LIN interfaces, but the TLE7269G includes a separate VIO supply while the TLE7259-2GE family uses an RxD pull-up arrangement. Review supply limits, wake-up polarity, logic thresholds, protection levels, and ordering-code quality requirements before substituting either part in an automotive design.
LIN is slower and more noise-tolerant than high-speed differential buses, but vehicle modules still contain switching and inductive loads. Keep switching-regulator high-current loops compact, separate motor-drive return paths from the transceiver ground, and avoid routing LIN beneath high-dv/dt copper. If communication errors occur under load, inspect the bus waveform at the connector and verify that the external pull-up and termination match the network topology specified by the manufacturer.
