TLE8457CSJXUMA1 - 20kBd LIN Transceiver | Infineon
MPN: TLE8457CSJXUMA1 ✓ সক্রিয়TLE8457CSJXUMA1 সারাংশ
A LIN transceiver, also called a LIN interface or LIN physical-layer device, connects a low-speed serial network controller to a vehicle communication bus. In the broader hierarchy, it belongs to the LIN interface transceiver class, interface IC category, and automotive semiconductor ecosystem. Integrating the voltage regulator with the bus interface reduces the number of external power components needed in compact automotive modules while preserving a stable 5 V supply for the local controller and peripherals.
The TLE8457CSJ family combines a LIN transmitter, LIN receiver, and low-dropout regulator in one integrated circuit. Its 20 kbit/s LIN data rate suits body electronics and comfort systems, while the 70 mA regulator output is intended for local microcontroller support rather than high-current loads. A low standby current of 20 µA is specified for the device family, helping reduce quiescent consumption when an automotive module enters a low-power state.
The PG-DSO-8 package is designed for surface-mount assembly and is associated with an automotive qualification grade of AEC-Q100. The device is identified with a one-transmitter, one-receiver configuration, and its RoHS 3 compliant and REACH unaffected declarations support use in modern automotive electronics supply chains. Moisture sensitivity is listed as MSL 3 for 168 hours, making controlled handling and reflow-profile management important during manufacturing.
Typical uses include LIN-controlled door modules, seat and climate-control electronics, body-control interfaces, sensor nodes, and compact automotive peripheral units. In each case, the transceiver handles the physical bus levels while the integrated 5 V regulator powers the local processing circuitry. Designers should also check the LIN bus topology, termination, transceiver enable behavior, wake-up requirements, and available regulator current before assigning a supply load to the internal LDO.
For a new PCB, follow the manufacturer pin-description table for signal assignment and place the input, output, and bus-decoupling components close to their associated pins. Keep the LIN bus routing away from sensitive analog and high-speed digital paths, and confirm that the chosen connector, ESD strategy, and grounding arrangement preserve the integrity of the physical layer.

সাধারণ ব্যবহার
TLE8457CSJXUMA1 এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Automotive Door Control Module, LIN Seat Control Electronics, Body Control Sensor Node, Climate Control LIN Interface, Automotive Switch and Relay Interface, Compact LIN Peripheral Unit.
Automotive Door Control Module
The TLE8457CSJXUMA1 fits a LIN-connected door module where the bus interface and local 5 V supply share a compact PG-DSO-8 footprint. Its one-transmitter, one-receiver arrangement communicates at up to 20 kbit/s, while the integrated regulator provides up to 70 mA for a local controller, input conditioning, and peripheral logic. This integration reduces the number of devices and board area required near a door wiring harness. Keep total regulator demand below 70 mA, validate wake-up and standby behavior, and route the LIN bus away from sensitive door-lock and body-sensor circuitry.
LIN Seat Control Electronics
A seat-control slave can use the TLE8457CSJXUMA1 to join a LIN network while powering its local controller from the integrated 5 V regulator. The 20 kbit/s bus rate is appropriate for typical LIN body electronics, and the 70 mA output avoids requiring a separate regulator for modest sensor and switch-handling loads. The 20 µA standby specification also supports low-power module strategies where long idle periods are common. Confirm that motor drivers, heating elements, and other high-current functions remain outside the regulator budget and are supplied separately.
Body Control Sensor Node
The TLE8457CSJXUMA1 is suitable for a compact LIN sensor node that combines bus communication with a regulated local supply. Its 5 V output of up to 70 mA can support a microcontroller, low-power sensing circuitry, and associated interfaces when their combined demand remains within the limit. AEC-Q100 qualification is relevant for automotive deployments, while RoHS 3 and REACH declarations support environmentally controlled sourcing. Check the exact operating-temperature range, ESD requirements, and wake-up behavior against the sensor module environment before design release.
Climate Control LIN Interface
In a climate-control peripheral, the TLE8457CSJXUMA1 can connect a microcontroller to the vehicle LIN network and supply the associated low-power electronics from its integrated 5 V regulator. The 20 kbit/s LIN rate matches common body-network control tasks, while the 1/1 transmitter and receiver configuration provides the required physical layer. The internal regulator is useful for position sensing, buttons, and logic but not for fan motors or heaters. Preserve clear separation between LIN routing, switchgear noise, and analog sensor paths to maintain signal quality.
Automotive Switch and Relay Interface
A LIN smart-switch module can use the TLE8457CSJXUMA1 to receive commands and provide a regulated supply for its local logic. The integrated 70 mA, 5 V regulator is appropriate for control electronics, status indicators, and low-power driver stages, but high-coil or high-current relay loads must use separate drive circuitry. The PG-DSO-8 package supports compact surface-mount construction, and the device's AEC-Q100 grade suits automotive qualification programs. Validate transient behavior at the connector and confirm the LIN transceiver's fault and wake-up requirements.
Compact LIN Peripheral Unit
The TLE8457CSJXUMA1 supports small LIN peripheral units that need communication and local power without occupying a large PCB area. Combining a one-driver, one-receiver LIN interface with a 5 V regulator output of up to 70 mA simplifies the architecture of low-cost automotive slaves. Its 20 kbit/s data rate supports standard LIN command and status traffic, and the 20 µA standby current favors low-power states. Use the manufacturer application guidance to select bus termination and supply decoupling, and maintain margin for startup and load transients.

ডিজাইন নোট
Budget the TLE8457CSJXUMA1 integrated regulator for no more than 70 mA, including the local controller, sensors, indicator loads, and startup peaks. Use the manufacturer regulator application circuit and pin configuration to select input and output capacitance. Keep high-current relay, motor, heater, and LED loads on a separate supply path; attempting to drive them from the internal regulator can cause voltage droop, unwanted resets, or thermal stress.
Place the LIN transceiver and regulator decoupling components close to the associated PG-DSO-8 pins, with the shortest practical return path to the ground reference. Follow the manufacturer layout guidance for the LIN bus connection and keep copper away from sensitive antenna, sensor, and audio routes. Because the exact pin names and recommended capacitor values are not stated on the product page, verify them in the TLE8457CSJ datasheet before releasing the PCB artwork.
Do not infer generic SOIC-8 pin assignments for this LIN transceiver and integrated regulator. Use the TLE8457CSJ pin-description table to distinguish LIN bus, supply, regulator output, enable, and ground functions, including any exposed thermal pad requirements. Also check wake-up polarity, sleep behavior, bus fault handling, and the valid operating-voltage range before connecting a node to the vehicle network.
Route the LIN bus as a controlled network rather than as a general-purpose high-speed signal. Apply the correct bus termination, use a protected connection to the harness, and avoid long parallel branches or unprotected stubs. Keep switching-node copper and high-current return paths separated from LIN_RX and related sensing circuits to reduce susceptibility to transient noise and ground bounce in the automotive electrical environment.
