TLE8458GXUMA2 - 5V LIN Transceiver with Vreg | Infineon
料号： TLE8458GXUMA2 ✓ 量产中TLE8458GXUMA2 概述
A LIN transceiver is a physical-layer interface within the broader automotive networking hierarchy. LIN, meaning Local Interconnect Network, is a low-cost serial bus used for distributed vehicle functions such as body electronics, climate-control modules, door controls, lighting, seat controls, and sensor interfaces. A LIN physical-layer transceiver converts logic-level serial data into a bus signal, provides receiver discrimination and fault-tolerant bus behavior, and works with the vehicle's 12 V electrical environment.
The TLE8458GXUMA2's principal headline specifications are its integrated 5 V regulator, 10.4 kBd LIN communication rate, and 8-pin DSO package. Integrating the regulator and transceiver can reduce the number of discrete power-supply components near a LIN-connected controller. The regulator output is intended to support the local electronic control unit, while the transceiver provides the connection to the LIN bus. Its integrated architecture also helps keep the power and communication interfaces within one compact device.
The device belongs to Infineon's TLE8458Gx family, whose described derivatives include TLE8458GV33, TLE8458GU, and TLE8458GUV33. The available TLE8458Gx family information also identifies compatibility with standalone LIN transceiver functions associated with TLE7259-2GE, although exact package-body equivalence and every electrical limit must be checked before treating that relationship as a PCB drop-in replacement.
Typical applications include LIN-connected automotive body-control modules, door and window control units, climate-control panels, ambient-light sensors, seat and roof controllers, switch and actuator modules, and other low-bandwidth vehicle subsystems. These applications benefit from the combination of a local 5 V supply and a LIN bus interface when the module contains a microcontroller requiring both regulated power and vehicle-network communication.
A key design consideration is that the LIN bus side operates in an automotive environment while the regulator serves sensitive electronics. Designers should follow the manufacturer's recommended input, output, transceiver, decoupling, grounding, and protection requirements from the official datasheet. Because the supplied verified data does not include complete absolute maximum ratings or detailed pin assignments, those values must not be inferred from generic LIN-transceiver families.
This page consolidates verified distributor classifications, family derivatives, package information, and application-oriented engineering guidance. It distinguishes confirmed drop-in family variants from unverified cross-brand equivalents and identifies missing electrical, pricing, pinout, and compliance data transparently rather than estimating values that could compromise an automotive design.

典型应用
TLE8458GXUMA2 适用于 6 应用s: Automotive Body-Control Module, Climate-Control Panel, Door and Window Control Unit, Seat and Roof Controller, Vehicle Lighting Module, Automotive Sensor Interface.
Automotive Body-Control Module
The TLE8458GXUMA2 fits a body-control module because its integrated 5 V regulator can support a local controller while the 10.4 kBd LIN transceiver connects that controller to the vehicle network. This integration reduces the component count around a LIN node and avoids a separate regulator footprint. The 8-pin PG-DSO-8-16 package also supports compact surface-mounted modules. Before release, verify the official input range, regulator-current capability, thermal limits, and automotive qualification against the module's worst-case load and temperature.
推荐
Climate-Control Panel
A climate-control panel is a natural application for the TLE8458GXUMA2 because it needs both low-bandwidth communication with the vehicle and power for a local controller or display interface. The 10.4 kBd LIN rate suits command, status, and sensor traffic rather than multimedia data. The integrated 5 V regulator can organize the local power architecture around one device. The designer must still budget regulator thermal dissipation at the highest panel load and confirm that the verified package drawing provides adequate copper and assembly clearance.
推荐
Door and Window Control Unit
The TLE8458GXUMA2 can support door or window control nodes that exchange switch, motor-driver, and diagnostic information over LIN. Its 10.4 kBd rate is appropriate for a low-bandwidth in-vehicle subnet, while the integrated 5 V regulator supplies nearby control electronics. The integrated design is especially useful where component count and PCB area are constrained. Validate wake-up, bus fault, ESD, and regulator-current behavior using the official datasheet because those limits are not present in the supplied search extracts.
推荐
Seat and Roof Controller
Seat and roof controllers benefit from the TLE8458GXUMA2 because they are compact LIN nodes combining vehicle-network communication with local regulated power. A single IC can address the control-IC supply and communication interface without duplicating a separate 5 V regulator section. Its 10.4 kBd LIN performance is suitable for motor-position and switch-status information. The implementation should use the manufacturer's recommended PCB layout and protection network, and confirm that regulator heat dissipation remains acceptable under the highest motor-control electronics load.
推荐
Vehicle Lighting Module
The TLE8458GXUMA2 is suitable for a LIN-connected lighting module that needs regulated logic power and a vehicle bus interface. Lighting modules commonly distribute commands and status information rather than high-bandwidth data, making the 10.4 kBd LIN rate appropriate. The integrated regulator can simplify the local supply path, while the 8-pin surface-mount package preserves PCB area. Engineers must check whether the specific module requires a higher regulator current, different fault behavior, or a package variant with confirmed automotive qualification.
推荐
Automotive Sensor Interface
The TLE8458GXUMA2 can serve as the network and power interface in a LIN-connected sensor module where the sensing circuit requires a local 5 V rail. The 10.4 kBd bus rate is suitable for slow sensor values, diagnostic information, and configuration commands. Integration allows the module to minimize component count without relying on a high-bandwidth network protocol. The circuit designer should confirm standby-current behavior, regulator accuracy, LIN common-mode limits, and ESD requirements from the official datasheet before selecting external protection and filtering components.

关键差异点
- Integrated local power and communication （对比 Standalone LIN transceivers such as TLE7259-2GE)
- Vehicle-network data rate （对比 Higher-bandwidth CAN or Ethernet transceivers)
- Compact surface-mount integration （对比 Discrete LIN transceiver-plus-regulator designs)
设计说明
Do not assume that the confirmed 5 V regulator output guarantees sufficient load current for every LIN node. Check the official maximum output-current limit, dropout behavior, thermal dissipation, and minimum load or stability requirements. The available search data does not include those numerical limits, so they must be extracted from Infineon's datasheet before capacitors, output loading, or copper area are finalized.
Use the manufacturer's PG-DSO-8-16 land pattern and verify the exposed-pad or thermal-pad geometry against the official package drawing. Place the regulator input/output capacitors and LIN bus components according to the reference layout, keeping high-current and high-di/dt return paths short. A nominal '8-pin DSO' description alone is insufficient to establish land-pattern compatibility between suffix variants.
Do not treat family-level pin compatibility as proof that every TLE8458Gx ordering code is interchangeable. Confirm the LIN input/output pin functions, regulator-output pin, enable or sleep behavior, ground connection, package dimensions, temperature grade, and automotive qualification for each suffix. Also verify the official limits before selecting termination, bus protection, or transceiver wake-up components.
The LIN bus is an automotive single-wire network, so layout and external-network component values must follow the official reference design. Keep the bus path away from sensitive sensor and audio traces, provide the specified return path to the vehicle ground system, and use the recommended protection network at the connector. EMC performance depends on the complete PCB, harness, filter, and bus topology rather than the transceiver marking alone.
合规信息
The verified sources classify the TLE8458GXUMA2 as an automotive device but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown pending the manufacturer product declaration or datasheet.
