TLE72592GEXUMA4 - 20 kBaud LIN Transceiver | Infineon
料号： TLE72592GEXUMA4 ✓ 量产中TLE72592GEXUMA4 概述
A LIN transceiver is an interface IC that connects a microcontroller or other host controller to a low-cost, single-wire automotive network. It converts serial logic-level commands into the electrical signaling used on the LIN bus and receives bus activity back into the host. The TLE7259-2GE family also integrates wake-up and protection functions for use in in-vehicle networks.
The TLE72592GEXUMA4 provides a maximum LIN data rate of 20 kBaud and a minimum supported rate of 2.4 kBaud. Its 1-transmitter, 1-receiver arrangement supports half-duplex communication, with the transmitter and receiver sharing access to the LIN conductor. The listed receiver hysteresis is 300 mV, a parameter involved in determining the noise margin for received bus signals.
The device operates from a 7 V to 27 V supply, allowing it to interface with conventional automotive electrical systems. Its PG-DSO-8-16 package has eight terminals, a gull-wing surface-mount form, and a maximum seated height of 1.73 mm. The listed moisture sensitivity classification is MSL 2A for a four-week floor-life period, which requires controlled handling and appropriate soldering practices.
Typical applications include LIN-connected vehicle body-control modules, door and seat controllers, climate-control interfaces, lighting controllers, sensor gateways, and other automotive electronic nodes. The 2.4 kBaud to 20 kBaud range covers common LIN communication tasks involving switches, actuators, and simple sensors.
When designing the LIN node, verify that the host controller logic levels, transceiver supply, ground reference, bus termination, and wake-up configuration match the vehicle network architecture. Place the transceiver close to the LIN connector and route the bus conductor away from high-current switching paths to reduce coupling into this low-speed, single-wire network.
This page combines the manufacturer's LIN transceiver characteristics with package, environmental, application, and replacement guidance. It also distinguishes exact drop-in candidates from broader LIN interface options so engineers can assess footprint, communication-rate, and protection considerations before changing an automotive design.

典型应用
TLE72592GEXUMA4 适用于 6 应用s: Vehicle Door and Seat Control Modules, Climate-Control and HMI Gateways, Automotive Lighting Controllers, Vehicle Sensor Gateways, Wake-Up Body-Control Modules, Diagnostic and Communication Hubs.
Vehicle Door and Seat Control Modules
The TLE72592GEXUMA4 fits LIN-connected door, seat, and access-control modules because it combines one transmitter and one receiver with data rates from 2.4 kBaud to 20 kBaud. Install it between the module's microcontroller and the single-wire LIN subnet, using the integrated wake-up function to support a low-power vehicle network. The 7 V to 27 V supply range accommodates conventional automotive battery environments. For a body actuator or switch, the host controller can command the remote node while receiving its status over the same conductor. Confirm the wake-up polarity and protection limits in the Infineon manufacturer datasheet before finalizing the network connection.
推荐
Climate-Control and HMI Gateways
The TLE72592GEXUMA4 is appropriate for climate-control peripherals and human-machine interface gateways that exchange commands and sensor status over LIN. Its maximum 20 kBaud rate is sufficient for typical LIN subnetwork traffic, while the minimum 2.4 kBaud setting allows slower, power-constrained nodes to participate. Place the transceiver near the LIN harness connection and route the bus away from motor-switching and heater-control traces to limit electromagnetic coupling. The -40°C to 150°C operating range supports harsh cabin and engine-adjacent environments, provided the layout satisfies the package's grounding and exposed thermal requirements.
推荐
Automotive Lighting Controllers
The TLE72592GEXUMA4 can serve as the physical-layer interface in an automotive lighting controller or LIN lighting gateway. Its one-driver, one-receiver arrangement provides bidirectional half-duplex communication over the shared LIN conductor, and its 2.4 kBaud to 20 kBaud range supports command, diagnostic, and status traffic. Use the transceiver to isolate the host controller from the wired network while retaining wake-up capability for parked vehicles. Verify the module's supply transient requirements, LIN termination arrangement, wake-up configuration, and bus protection limits against the Infineon manufacturer datasheet before production release.
推荐
Vehicle Sensor Gateways
The TLE72592GEXUMA4 is useful in a LIN sensor gateway that consolidates switches, position sensors, or simple actuator feedback from a vehicle subnet. Its receiver hysteresis of 300 mV contributes to signal-noise discrimination, while the maximum 20 kBaud rate supports ordinary LIN control traffic. The transceiver requires only one bus driver and one receiver, simplifying host-controller connections compared with adding separate discrete line-driver and receiver stages. Keep the LIN return path continuous, observe the recommended ground reference, and place protection and termination components where they will not create unintended stubs or excessive capacitive loading.
推荐
Wake-Up Body-Control Modules
The TLE72592GEXUMA4 is appropriate for a wake-up body-control module because the TLE7259-2GE family includes an integrated wake-up function alongside bus protection. The host microcontroller can remain in a low-power state while the transceiver detects the configured LIN wake-up condition and signals the controller. This architecture reduces unnecessary vehicle energy use without adding a separate bus receiver. The 7 V to 27 V operating range and -40°C to 150°C thermal rating support automotive electrical environments. Validate the wake-up pulse shape, pin polarity, bus capacitance, and system sleep-current budget using the manufacturer's application guidance.
推荐
Diagnostic and Communication Hubs
The TLE72592GEXUMA4 can form part of a vehicle communication hub that connects a host controller to a LIN branch carrying diagnostic or node-status data. At up to 20 kBaud, the interface supports the bandwidth expected of conventional LIN networks, while the integrated protection features help the node withstand automotive harness transients. The small 8-pin PG-DSO-8-16 package allows placement near a connector or harness branch. Because LIN is a single-wire network, keep the board's bus geometry short, provide the specified ground reference, and avoid routing the LIN trace parallel to high-current inductive loads or switching nodes.

设计说明
Route the LIN connection as a short, controlled-impedance harness interface from the TLE72592GEXUMA4 to the connector or bus branch. Keep the trace away from switching-node copper, relay coils, motor windings, and high-current return paths to reduce electromagnetic coupling. Provide a continuous ground reference and avoid long stubs between the transceiver and termination components. Confirm the final PCB placement against the Infineon manufacturer datasheet application circuit and package drawing.
The transceiver operates from 7 V to 27 V, but the surrounding module must still manage automotive supply transients and ensure that the TLE72592GEXUMA4 receives a clean local supply. Place recommended input capacitance and any protection components close to the supply and ground pins, with a low-impedance return to the device. Verify the wake-up current contribution against the module sleep budget and use the manufacturer guidance to confirm the required supply decoupling.
Do not substitute a LIN transceiver solely because its data rate and package count appear similar. Check the exact LIN pinout, TXD and RXD polarity, wake-up pulse definition, receiver thresholds, protection behavior, supply limits, and automotive qualification. After any replacement, verify bus termination, dominant-state behavior, sleep and wake transitions, and communication at both 2.4 kBaud and 20 kBaud before releasing the design.
Follow the PG-DSO-8-16 land pattern and solder-mask recommendations in the Infineon manufacturer datasheet. Preserve the package pin-1 orientation, inspect the terminals after reflow, and account for the listed MSL 2A handling classification. Because the maximum seated height is 1.73 mm, check connector, shielding, and enclosure clearances before releasing the mechanical design.
