TLIN1039-Q1 개요
A LIN transceiver is the physical-layer interface for the LIN (Local Interconnect Network) bus, a single-wire, low-speed serial protocol widely used for in-vehicle body and comfort networks such as door modules, seat controllers, mirror switches, and HVAC actuators. The TLIN1039-Q1 belongs to the family of automotive LIN transceivers within the broader category of interface ICs / physical-layer transceivers, sitting beneath the CAN/LIN/FlexRay hierarchy of in-vehicle networking standards. Its role is to translate CMOS-level TXD/RXD logic into the dominant/recessive current-driven LIN bus waveform that meets the LIN 2.0/2.1/2.2/2.2A, ISO/DIS 17987-4 and SAE J2602-1 physical-layer specifications.
Key features of the TLIN1039-Q1 include integrated local and remote wake-up support, a current-limited wave-shaping driver that reduces electromagnetic emissions (EME), an open-drain RXD output for flexible logic interfacing, internal pull-down on TXD for fail-safe behavior, dominant-state time-out protection, and ±45 V bus-fault tolerance with thermal shutdown. The combination of wide operating voltage, bus-fault ruggedness and AEC-Q100 Grade 1 qualification makes the part well suited to harsh automotive electrical environments including jump-start, load-dump and reverse-battery transients.
Architecturally, the device combines a bandgap-referenced voltage regulator, a current-limited open-drain LIN driver with slew-rate control, a window comparator receiver, and a state-machine that handles dominant time-out, thermal shutdown, under-voltage lockout and wake-up detection. The integrated ESD cell on the LIN pin exceeds ±8 kV HBM, eliminating the need for an external TVS in most 12-V automotive LIN node designs.
Typical applications include body control modules, door/window/seat/mirror modules, HVAC control nodes, steering column switches, lighting ECUs, and sensor/actuator nodes that must interface with a LIN master in an in-vehicle network. The receiver's higher 100 kbps capability also enables faster in-line programming of slave ECUs over the LIN bus.
When designing with this device, ensure that VSUP is decoupled with a 100 nF ceramic capacitor close to the pin, and that the LIN bus pin is protected by the bus-pin ESD structure rather than an external TVS, since adding a TVS can load the bus and disturb the LIN waveshaping. The TXD pin must not be pulled high to VSUP, as TLIN1039-Q1 only provides an internal pull-down.

일반적인 애플리케이션
TLIN1039-Q1 적합 용도: 7 애플리케이션s: Automotive Body Control Module (BCM), Door Module / Seat / Mirror LIN Slave ECU, HVAC Control and Blower ECU, Steering Column Switch Module, Lighting ECU / Ambient Light Node, Sensor / Actuator LIN Node, In-Line Programming over LIN.
Automotive Body Control Module (BCM)
The TLIN1039-Q1 fits a BCM (body control module) because of its 4.5 V to 36 V supply range and ±45 V bus-fault protection, which survive 12-V battery transients including jump-start and load-dump without external bus protection. The LIN bus connects BCMs to door/window/seat/mirror/HVAC slave ECUs; the part's integrated wake-up, dominant time-out, and thermal shutdown let the BCM drive dozens of slave nodes reliably. The 20 kbps TX rate matches the LIN 2.x physical-layer specification used in BCMs, while the 100 kbps RX rate speeds ECU re-flashing during service.

Door Module / Seat / Mirror LIN Slave ECU
Window lifters, seat positioners and power mirror slave ECUs run on LIN to cut wiring harness weight. The TLIN1039-Q1's TSOT-23-8 footprint and AEC-Q100 Grade 1 qualification fit the tight PCB inside a door module, where the ±45 V bus-fault tolerance handles motor back-EMF and reverse-battery conditions without a TVS on the LIN pin. The dominant-state time-out prevents a stuck-dominant condition from blocking the entire LIN bus when a slave ECU fails, improving network robustness across all door/window/seat/mirror nodes.
추천
HVAC Control and Blower ECU
HVAC head units and blower modules use LIN to drive climate flaps and fans. The TLIN1039-Q1 supports this application with integrated local and remote wake-up so the HVAC node can be commanded by the BCM without a CAN-LIN gateway, simplifying network topology. Its internal pull-down on TXD guarantees a recessive idle state when the MCU TXD is tri-stated at startup, eliminating spurious LIN frames that would otherwise confuse the LIN master.
추천
Steering Column Switch Module
Steering column switch clusters (turn signal, wiper, light stalk) communicate with the BCM over LIN. The TLIN1039-Q1 fits this application because the small TSOT-23-8 footprint fits inside the tight stalk housing, the AEC-Q100 Grade 1 qualification handles -40 C to +125 C cabin-temperature extremes near the windshield, and the current-limited wave-shaping driver reduces EME that would otherwise couple into the adjacent analog wiper-position sense traces.
추천
Lighting ECU / Ambient Light Node
Interior and exterior lighting ECUs (headlamp, tail lamp, RGB ambient) increasingly use LIN for LED driver control. The TLIN1039-Q1 supports 12-V body networks with ±45 V bus-fault tolerance, which is critical when the lighting module shares wiring near inductive loads. The 100 kbps RX rate allows fast re-flashing of LED firmware over LIN without removing the part from the vehicle, which simplifies end-of-line programming.
추천
Sensor / Actuator LIN Node
Battery sensors, rain/light sensors, and occupancy sensor ECUs typically sit on LIN to reduce harness weight. The TLIN1039-Q1's low VSUP quiescent current and remote wake-up capability enable sleep currents below the LIN bus-specification wake threshold, supporting ISO/DIS 17987-4 sleep/wake cycles. The integrated ±8 kV HBM ESD on the LIN pin lets the sensor node survive handling and harness assembly without an external TVS.
추천
In-Line Programming over LIN
Service technicians re-flash ECUs over LIN using the 100 kbps receiver mode of the TLIN1039-Q1. Because the receiver path supports up to 100 kbps while the transmitter remains at the LIN-spec 20 kbps, the part enables faster boot-loader transfers without violating the LIN physical-layer transmit waveform. This shortens service-bay reprogramming time for door modules, HVAC nodes, and lighting ECUs without modifying the master LIN stack.

설계 노트
Place a 100 nF X7R ceramic decoupling capacitor as close as possible to the VSUP pin and a 100 nF capacitor on the LIN pin near the package body to satisfy the LIN physical-layer EME/EMI budget. Use a four-layer PCB with a continuous ground plane under the TSOT-23-8 thermal pad; stitch vias around the thermal pad to the inner ground plane to keep the LIN bus impedance at the recommended 30 ohms nominal load.
Do NOT add an external TVS diode (such as ESD1LIN24-Q1) on the LIN bus pin unless the design is exposed to IEC 61000-4-2 air-discharge levels above ±8 kV. The TLIN1039-Q1 already integrates ±8 kV HBM and IEC ESD protection on the LIN pin; adding a TVS loads the bus and distorts the LIN waveshaping, causing EME failures during compliance testing. The TXD pin has an internal pull-DOWN: pulling it to VSUP or VCC will create a stuck-dominant condition. Do not connect TXD to VSUP.
Estimated: With a LIN bus capacitance budget of 220 pF (cable + 1 slave node + protection), the TLIN1039-Q1's current-limited wave-shaping driver produces a 20 kbps rise time of approximately 2 us to 4 us, which is well inside the LIN 2.x EME mask. If the bus capacitance exceeds 470 pF (long cable or >4 nodes), the rise time slows and the bus may fail EME; in that case, lower the bit rate or add a series resistor at the LIN pin to slow the edge further.
VSUP may be tied to the battery rail directly. The internal regulator for the digital core draws approximately 2 mA in normal operation and below 20 uA in sleep mode. Add a reverse-battery blocking diode (such as MBRS1100T3G) in series with VSUP if the load-dump protection is not provided elsewhere in the wiring harness. The thermal pad must be soldered to a copper pour of at least 50 mm^2 to keep junction temperature within limits at +125 C ambient.
