TLE8457ASJXUMA1 - 5V 20kBd LIN Transceiver | Infineon
MPN： TLE8457ASJXUMA1 ✓ 啟用中TLE8457ASJXUMA1 概覽
A LIN transceiver, also called a Local Interconnect Network transceiver, connects a microcontroller or programmable logic controller to a LIN bus. It converts serial bus-level signals into digital receive and transmit signals for the host controller. This TLE8457ASJXUMA1 combines that interface function with a local regulator, reducing the number of components needed for a compact LIN node while preserving a stable 5 V supply for digital circuitry.
The principal features include a regulated 5 V output, an output capability of up to 70 mA, LIN operation at up to 20 kBd, and a low-dropout regulator integrated into the same monolithic device. The half-LIN-bus transceiver designation identifies the device as a one-channel communications solution. These characteristics make it suitable for distributed automotive subsystems where a controller must exchange low-speed serial data with remote modules over a cost-effective single-wire network.
Typical uses include automotive body-control modules, door and seat electronics, climate-control panels, sensor nodes, and LIN-connected switches. In these systems, the microcontroller can use the transceiver's receive and transmit interface to exchange commands and diagnostic information with remote LIN slaves. The integrated regulator can support nearby low-power peripherals when the board-level power budget remains within the device's 70 mA capability.
Design the PCB with a clear return path for the LIN bus, robust input filtering, and protection appropriate to the vehicle electrical environment. Place the regulator output capacitor and transceiver interface components close to their associated pins to limit trace inductance and high-frequency disturbance. Verify the LIN waveform, bus rise time, termination, and system sleep behavior against the device requirements and the LIN standard used by the vehicle platform.
This product page combines the manufacturer's device description with package, interface, application, and replacement guidance. It also highlights the distinction between the DSO-8 distributor package name and the TSON-8 manufacturer package name, helping engineers cross-check footprints before committing a PCB design to this integrated LIN transceiver and 5 V regulator.

典型應用
TLE8457ASJXUMA1 適用於 6 應用s: Automotive Body Control Modules, Door and Seat Control Modules, Automotive Climate-Control Panels, LIN-Connected Sensor Nodes, Switches and Actuator Controllers, Vehicle Lighting Control Modules.
Automotive Body Control Modules
TLE8457ASJXUMA1 fits compact body-control modules that exchange commands and status with LIN-connected modules while powering a local controller. The integrated 5 V regulator provides up to 70 mA, allowing a low-power microcontroller and limited peripherals to share the device when their combined demand remains below that limit. The LIN interface operates up to 20 kBd, and the 8-pin DSO package supports dense automotive PCB layouts. Its AEC-Q100 qualification makes it appropriate for automotive qualification programs, provided the final node meets voltage, transient, sleep-current, and communication-timing requirements.
推薦
Door and Seat Control Modules
A door or seat control module can use TLE8457ASJXUMA1 as the LIN node interface and local 5 V supply source. The 20 kBd LIN capability supports standard low-speed vehicle body-network communication, while the regulator's 70 mA maximum output is suitable for a controller and modest sensor or indicator loads. The integrated 8-pin DSO package reduces board area compared with separate transceiver and regulator arrangements. During qualification, verify bus rise time, sleep current, wake-up behavior, load transients, and the controller's current budget under all vehicle operating states.
推薦
Automotive Climate-Control Panels
TLE8457ASJXUMA1 is appropriate for climate-control panel electronics that use LIN for distributed button, sensor, or actuator communication. The integrated 5 V regulator can serve a compact controller and low-power interface circuitry up to its 70 mA capability, reducing the number of local supply components. The 8-pin DSO footprint is useful where panel PCB area is constrained. Validate standby and sleep behavior, startup sequencing, LIN signal integrity, EMC performance, and the total panel load before selecting the device for production.
推薦
LIN-Connected Sensor Nodes
TLE8457ASJXUMA1 can serve as the communications and power interface in a remote LIN sensor node. Its one-half-LIN-bus transceiver handles the serial physical layer at rates up to 20 kBd, while the integrated low-dropout regulator provides a stable 5 V rail with up to 70 mA available for a sensor, microcontroller, and associated logic. The integrated function is especially useful where the node must remain compact and low power. Ensure the total peak current remains within the regulator limit and check wake-up, sleep, and bus-fault requirements against the node specification.
推薦
Switches and Actuator Controllers
TLE8457ASJXUMA1 fits distributed switch or actuator controllers that accept commands over LIN and need a local regulated supply. A single 8-pin device combines the 20 kBd LIN physical interface with a 5 V regulator capable of delivering up to 70 mA. This can support a low-power controller and limited driver logic where the actuator itself is powered separately. During design-in, confirm actuator load separation, transient control, LIN timing margins, and thermal performance so the transceiver and regulator are not exposed to loads outside their intended roles.
推薦
Vehicle Lighting Control Modules
TLE8457ASJXUMA1 can support compact vehicle lighting-control modules that receive commands over a LIN network and operate a low-power logic section. Its integrated 5 V regulator reduces the supply-component count, while the 70 mA output capability must be compared with the logic and indicator-driver loads. The 20 kBd LIN interface is appropriate for slow supervisory communication rather than high-bandwidth lighting data. Validate lamp-load separation, transient immunity, standby consumption, thermal margin, and the lighting module's LIN diagnostic requirements before production use.

設計說明
Budget the integrated regulator's total load against the documented 70 mA maximum, including the microcontroller, pull resistors, interface logic, and startup transients. Keep the LIN transceiver's supply current separate from the regulated peripheral load in the power budget. Confirm the battery-side input range, dropout behavior, and regulator thermal performance under the vehicle's worst-case supply and temperature conditions before layout release.
Use the Infineon TSON-8 land pattern and pin table as the controlling references for PCB layout because distributor records may label the package DSO-8 or PG-DSO-8. Place the regulator capacitor and LIN interface components close to their pins, maintain a compact ground return, and avoid routing sensitive signal paths beside the bus conductor. Confirm exposed-pad requirements and solder-mask geometry against the exact manufacturer package drawing.
Validate the complete LIN physical layer rather than checking only logic-level operation. Measure bus rise time, dominant and recessive levels, symmetry, receiver thresholds, and timing margin at up to 20 kBd across the intended wiring lengths. Keep the LIN route away from switching nodes and high-current edges, and verify that the connector, protection network, and test points do not distort the bus waveform.
Do not assume that a related TLE8457 suffix is automatically interchangeable. Before substituting a candidate, compare the exact pin table, LIN slew-rate limits, regulator dropout, output-current capability, sleep current, wake-up behavior, and qualification status. A package drawing with the same pin count is not sufficient evidence of drop-in compatibility when functional or timing differences are undocumented.
