TLIN10283DRBRQ1 Overview
A LIN transceiver is the physical-layer interface IC that converts the UART data stream of a microcontroller into the dominant/recessive differential signaling used on a LIN bus. Within the system hierarchy, it sits between the MCU (logic domain) and the vehicle wiring harness (12V physical domain), and when combined with an LDO it forms a LIN system basis chip (SBC) - a subset of full automotive network processors.
Key features include an integrated 3.3V LDO regulator delivering up to 125 mA for the local MCU or sensors, LIN 2.2A / ISO/DIS 17987-4 protocol compliance for interoperability across vehicle platforms, AEC-Q100 automotive qualification for harsh 12V environments, and low quiescent power operation with wake-up support on the LIN bus. The 3x3 mm VSON package with exposed pad enables compact ECU node designs.
Technically, the device integrates the LIN line driver and receiver with stringent output slew control to meet the 20 kbps (maximum) LIN data rate while minimizing EMC emissions, plus protection features such as loss-of-ground and load-dump tolerance typical of TI LIN SBCs. The LDO eliminates an external 3.3V regulator, reducing BOM count and PCB area in each node.
Typical applications include body control modules, window/seat/door zone control units, HVAC actuators, and sensor nodes distributed across a 12V automotive LIN network.
A key design consideration: verify that the total current drawn by the local MCU and sensors stays within the 125 mA LDO budget, and use a large enough exposed-pad copper area for thermal dissipation in dense nodes.

Typical Applications
TLIN10283DRBRQ1 is suitable for 6 applications: Body Control Module (BCM), Door / Seat / Window Zone Control Units, HVAC and Climate Control Nodes, Automotive Sensor Nodes and Liquid-Level / Position Sensing, Lighting Control Modules (Interior and Exterior LIN Lighting), Gateway and Sub-Bus Aggregation in 12V ECUs.
Body Control Module (BCM)
The TLIN10283DRBRQ1 fits body control modules where a main MCU coordinates several LIN sub-nodes such as lighting, latching, and wiper control. Its LIN 2.2A / ISO/DIS 17987-4 compliance guarantees interoperability with mixed-vendor nodes on the same bus, while the integrated 3.3V LDO (up to 125 mA on the DRB version) can power a local secondary MCU or watchdog, removing a discrete regulator from the BOM. The 5.5V to 28V supply range and AEC-Q100 qualification cover 12V battery load-dump conditions typical of BCM environments. Placed between the MCU UART and the LIN harness with its exposed-pad VSON-8 package grounded to a solid copper pour, the transceiver's controlled slew at 20 kbps keeps EMC emissions within automotive limits while ensuring robust dominant/recessive signaling across the vehicle harness.
Recommended
Door / Seat / Window Zone Control Units
Distributed zone ECUs inside doors and seats are classic LIN nodes: small PCB area, low data rate (20 kbps maximum), and only a local MCU plus motor drivers. The TLIN10283DRBRQ1's 3x3 mm VSON-8 (DRB) package minimizes footprint, and the integrated 3.3V rail with up to 125 mA output powers the local MCU directly from the 12V battery feed, eliminating a separate LDO in each door module - a significant cost saving multiplied across eight or more nodes per vehicle. AEC-Q100 qualification and -40C to +125C operation cover cabin thermal extremes such as sun-loaded door panels. During design, budget the MCU plus sensor current within the 125 mA LDO limit and provide adequate exposed-pad copper for thermal relief, since the small package dissipates LDO losses in a compact area.
Recommended
HVAC and Climate Control Nodes
HVAC systems use LIN to link flap actuators, blower controls, and temperature sensor nodes back to a central climate controller. The TLIN10283DRBRQ1 provides the physical-layer interface compliant to LIN 2.2A and ISO/DIS 17987-4, ensuring the node communicates correctly with OEM climate master modules. Its integrated 3.3V LDO (up to 125 mA) supplies local temperature-sensor ICs or a small MCU, simplifying the node power tree from a 5.5V to 28V battery input. The controlled output slew at the 20 kbps LIN rate reduces radiated emissions near sensitive blower-motor circuitry, while AEC-Q100 qualification and the -40C to +125C range withstand under-dash thermal cycling. Layout should keep the LIN pin trace short to the connector and place the VCC decoupling capacitor within 2 mm of the pin per standard TI LIN SBC layout guidance.
Recommended
Automotive Sensor Nodes and Liquid-Level / Position Sensing
Many LIN-based sensors - fluid level, pressure, position, and occupancy - pair a small sensing front-end with a LIN interface on a tiny PCB. The TLIN10283DRBRQ1 is well suited here because the integrated 3.3V LDO can power the sensing element and local MCU (within the 125 mA budget), so the entire node runs from just the 12V LIN supply line, often enabling 3-wire sensor architectures. The 5.5V to 28V input range tolerates crank and load-dump conditions, and AEC-Q100 qualification plus the -40C to +125C range meet underbody and engine-bay requirements. The VSON-8 3x3 mm exposed-pad package suits compact sensor housings; thermal design should account for LDO dissipation at high battery voltage - for example, at VSUP = 14V and 50 mA load, estimated LDO dissipation is about 0.5W, so verify junction temperature with the datasheet thermal metrics.
Recommended
Lighting Control Modules (Interior and Exterior LIN Lighting)
LIN is widely used for ambient interior lighting, LED matrix supervision, and exterior lamp status feedback. The TLIN10283DRBRQ1's LIN 2.2A / ISO/DIS 17987-4 compliance lets a lighting node join OEM LIN clusters, while its integrated 3.3V, up-to-125 mA regulator powers the local LED controller or MCU, trimming board space in slim light-bar housings. Controlled slew-rate switching at 20 kbps limits emissions that could couple into LED driver loops, an important EMC consideration in lighting assemblies. The AEC-Q100-qualified device operates from -40C to +125C, covering headlamp-adjacent temperatures. Designers should keep the LDO load budget in mind: an LED controller plus MCU must remain below 125 mA, and higher-current LED strings should be fed from a separate buck converter rather than the integrated 3.3V rail.
Recommended
Gateway and Sub-Bus Aggregation in 12V ECUs
In a domain/zonal E-E/E architecture, a central gateway often supervises multiple LIN sub-buses. Per TLIN10283DRBRQ1 channel, the transceiver links the gateway MCU to one LIN branch, and because the part is a LIN SBC with an integrated 3.3V/125 mA LDO, it can also power a local supervisor, CAN transceiver standby logic, or monitoring circuitry at that port. Its 5.5V to 28V supply range accepts 12V-rail variation, and LIN bus wake-up lets sleeping gateway branches be re-awakened on bus activity, supporting low-quiescent standby strategies. AEC-Q100 qualification covers the -40C to +125C automotive ambient. Verify that aggregate per-port LDO loads stay within 125 mA, and route each LIN line with series protection per the datasheet's typical application recommendations for ESD and transients.

Key Differentiators
- Integrated 3.3V LDO reduces BOM count per node (vs TLIN1027DRBRQ1)
- 3.3V rail matches modern MCUs directly (vs TLIN10285DRBRQ1)
- Compact 3x3 mm VSON-8 with exposed pad (vs TLIN10283DRQ1)
Design Notes
Budget the LDO load carefully. The TLIN10283DRBRQ1's integrated 3.3V regulator supplies up to 125 mA (DRB suffix) - sum the local MCU run current, sensor currents, and any external pull-ups on VCC and keep total below this limit across temperature. Estimated example: at VSUP = 14V with a 50 mA VCC load, LDO dissipation is roughly (14V - 3.3V) x 50 mA = 0.54W, so verify junction temperature against the datasheet thermal metrics with your PCB copper area. If the load exceeds budget, add a discrete buck such as the TPS57160QDGQRQ1 and consider the TLIN1027DRBRQ1 variant instead.
Use the exposed pad of the VSON-8 (DRB) 3x3 mm package as the primary thermal and ground path: connect it to a solid ground pour with an array of at least 4-5 vias to inner ground planes. Place the VCC output capacitor and VSUP input capacitor within 2-3 mm of their pins, following TI's LIN SBC typical application layout. Keep the LIN trace short and direct to the connector, and route it away from high dV/dt switching nodes (buck converters, motor drivers) to limit capacitive coupling onto the bus.
Do not use the TLIN10283DRBRQ1 in 24V truck systems: the 5.5V to 28V supply range targets 12V automotive batteries, and 24V load-dump transients can damage the transceiver and LDO, per TI/Xecor application guidance. Also, when substituting the TLIN1027DRBRQ1 (no LDO) into a TLIN10283 footprint, remember the VCC pin changes role from regulated output to external supply - leaving it unconnected will leave the MCU unpowered. Finally, confirm the exact DRB pin map against the latest TI datasheet revision before releasing the footprint.
