TJA1024HGZ - Quad 20 kBd LIN 2.2A Transceiver | NXP
MPN: TJA1024HGZ ✗ Son Kullanım ZamanıTJA1024HGZ Genel Bakış
A LIN transceiver, also called a LIN bus interface controller, is an integrated circuit that connects a host-side serial controller to a physical LIN subnetwork. It belongs to the hierarchy of bus interface IC, communication transceiver, vehicle network interface, and semiconductor. The TJA1024HGZ integrates four LIN channels, allowing one controller to connect to multiple low-speed vehicle-network nodes while retaining individual fault-management capabilities.
The TJA1024 family converts controller-generated data streams into LIN bus signals shaped to reduce electromagnetic emissions, as stated in the NXP datasheet excerpt. Its LIN bus outputs are pulled high through internal termination resistors. The part is software compatible with the TJA1022, TJA1027, and TJA1029, making it useful when an established LIN protocol stack must connect to this physical-layer transceiver.
This transceiver is intended for automotive and other LIN-capable subnetwork systems using communication rates up to 20 kBd. Potential circuit roles include body electronics, seat and door modules, climate-control interfaces, lighting controllers, and sensor gateways. The integrated quad-channel architecture can reduce the number of separate single-channel transceivers required on a controller board.
Design work should verify supply voltage, pin mapping, bus termination, transceiver enable/control behavior, fault handling, and signal integrity against the complete manufacturer datasheet before layout release. The supplied distributor record identifies a 5 V to 18 V operating feature, while detailed electrical limits, timing values, thermal limits, and pin names were not included in the verified excerpts and therefore remain unconfirmed here.
This product page combines the supplied manufacturer, distributor, and cross-reference evidence with practical engineering guidance. It distinguishes verified LIN standards and package information from unavailable specifications, helping designers identify the correct interface function without treating CAN alternatives as pin-compatible replacements.

Tipik Uygulamalar
TJA1024HGZ için uygundur 6 uygulamas: Automotive Body Control Gateway, Vehicle Door and Seat Module, Climate-Control Panel Interface, Lighting and Accessory Controller, Automotive Sensor Gateway, Industrial LIN-Compatible Control Module.
Automotive Body Control Gateway
The TJA1024HGZ fits a body or gateway controller that must bridge a host MCU or LIN-capable processor to four low-speed vehicle-network subnets. Its verified 20 kBd limit aligns with LIN 2.0, 2.1, 2.2, 2.2A, and SAE J2602 operation described by NXP. Four integrated channels can reduce the number of discrete physical-layer devices, while internal HIGH-side termination and emission-shaped bus signals support practical wiring. Before layout, verify the controller electrical interface, fault modes, supply behavior, protection requirements, and exact exposed-pad connection in the complete datasheet.
Önerilen
Vehicle Door and Seat Module
A door, seat, or access module can use the TJA1024HGZ when it communicates with multiple LIN nodes over subnetworks running up to 20 kBd. The four-channel configuration permits multiple bus connections in one controller package, provided the application requires the exact pin and channel functions of the 24-DHVQFN variant. The device supports the listed LIN specifications and shapes transmitted signals to minimize electromagnetic emissions. Layout should keep LIN routing controlled, apply the appropriate connector protection, and validate wake-up, sleep, ground-offset, and fault behavior from the manufacturer documentation.
Önerilen
Climate-Control Panel Interface
The TJA1024HGZ can serve as a physical-layer interface in a climate-control head unit that exchanges LIN commands with distributed control modules. Its verified support for baud rates up to 20 kBd and LIN 2.0 through 2.2A makes it relevant to low-bandwidth vehicle subsystems, while the quad-channel arrangement supports several LIN buses in one design. Signal shaping helps limit electromagnetic emissions, and internal termination supports bus-high biasing. Engineers must still confirm channel enable controls, fault recovery, current limits, and timing margins in the official NXP datasheet.
Önerilen
Lighting and Accessory Controller
The TJA1024HGZ is appropriate where a lighting or accessory controller must communicate with several LIN subnodes rather than a single bus. Its four transceivers can consolidate physical-layer channels, and the verified 20 kBd operating target matches typical low-speed control traffic. The internal pull-up arrangement and emission-shaped outputs assist bus integration, but board-level EMC still depends on connector placement, cable routing, shielding, and filtering. Validate the 5 V to 18 V feature against the complete electrical limits before selecting external protection and power architecture.
Önerilen
Automotive Sensor Gateway
A sensor gateway can use the TJA1024HGZ to connect a higher-level controller to multiple LIN-attached remote sensors. The four-channel architecture is useful where independent sensor buses terminate at one controller, while verified support through LIN 2.2A/SAE J2602 helps align the interface with established vehicle-network expectations. Because sensor links can be long and noisy, engineers should use controlled bus routing and suitable connector protection while confirming termination, recessive-state behavior, and fault handling from the manufacturer datasheet. The component does not replace sensor signal conditioning or protocol software.
Önerilen
Industrial LIN-Compatible Control Module
The TJA1024HGZ can also serve laboratory equipment or industrial controllers that deliberately use LIN-compatible subnets for distributed low-speed nodes. Its verified 20 kBd ceiling and support for LIN 2.0, 2.1, 2.2, 2.2A, and SAE J2602 make it relevant where interoperability with automotive-style LIN equipment is required. The four channels simplify multi-bus consolidation, but an industrial installation still needs deterministic wiring, documented termination, suitable cable lengths, and tested fault recovery. Confirm application-specific environmental and qualification requirements that were not supplied with the source excerpts.

Tasarım Notları
Keep each LIN route short, controlled, and away from sensitive analog or high-speed clock nets. Because the IC shapes signals to reduce electromagnetic emissions, PCB compliance should preserve the reference layout, return path, and termination arrangement described by NXP. Do not infer exposed-pad connectivity or duplicate the package pin map from an unverified diagram; confirm it against the official TJA1024 datasheet.
Do not substitute a CAN transceiver for this part merely because another distributor snippet labels it as CAN. TJA1024HGZ is a four-channel LIN device, while MCP2551, SN65HVD230, and ISO1042 are CAN-interface parts. Such a change alters the bus protocol, electrical design, pinout, and firmware requirements and therefore is not a drop-in replacement.
Treat the LIN connector, protection components, cable route, chassis or signal ground, and power return as one emissions-control system. The verified device output shaping can reduce conducted and radiated emissions, but layout still affects the result. Use the manufacturer reference layout, minimize loop area, place protection at the connector, and verify the finished network with the intended cable and load configuration.
The supplied LCSC record states a 5 V to 18 V feature, but the detailed absolute maximum and transient limits were not included. Confirm the exact supply requirements, startup behavior, sleep current, and fault-path limits in the official datasheet before selecting regulators or protection components. This is especially important in vehicle environments where load dump and supply disturbances may exceed nominal operating conditions.
Validate communication at the intended maximum 20 kBd rate with the expected wire length, termination, node count, ground offset, and sleep/wake states. The verified internal pull-up arrangement biases LIN outputs HIGH, but subsystem behavior can still be affected by external termination, protection leakage, and wiring. Use oscilloscope measurements at the connector and review controller timing margins against the complete datasheet.
Uyumluluk Bilgisi
The supplied excerpts identify LIN and SAE J2602 compliance but do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements.
