Product details
Overview
TLIN10285DRBRQ1 from Texas Instruments is an automotive-grade LIN System Basis Chip (SBC) integrating a LIN transceiver compliant with ISO/DIS 17987–4 and SAE J2602, a 3.3 V/5 V LDO regulator delivering up to 125 mA, and ultra-low-power sleep mode with bus- or EN-pin wake-up capability - deployed in body electronics, lighting, and powertrain nodes.
For engineers reviewing the TLIN10285DRBRQ1 datasheet, TLIN10285DRBRQ1 pinout, TLIN10285DRBRQ1 application, or TLIN10285DRBRQ1 equivalent, key selection criteria include LIN bus fault protection (±58 V), LDO output current capability (125 mA), AEC-Q100 Grade 1 qualification, functional safety documentation support, and VSON (8) package compatibility with automated optical inspection.
Technical Context
The TLIN10285DRBRQ1 implements a current-limited LIN bus driver with optimized wave-shaping to reduce electromagnetic emissions, and features an open-drain RXD output with internal pull-up to VSUP (45 kΩ) and configurable LDO output voltage (3.3 V or 5 V). It supports both commander and responder node topologies without external pull-up components for responder applications.
Its functional safety-capable architecture includes documented failure modes, diagnostic coverage indicators, and thermal shutdown (165 °C trip, 150 °C release) with 10 °C hysteresis. Sleep mode draws only 17–33 µA at 5.5–28 V VSUP, enabling low-power vehicle subsystems requiring wake-on-LIN functionality.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN transceiver + LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLIN1029DRBRQ1 | Same VSON-8 package and pinout; adds wake-on-RXD capability and improved DTO timing (20–34 ms vs. 20–80 ms) | Preferred for systems requiring additional wake-source flexibility or tighter dominant timeout control | Select TLIN1029DRBRQ1 when wake-on-RXD or tighter DTO spec is required; otherwise TLIN10285DRBRQ1 offers identical core functionality at lower cost |
| MC33664ELHR2 | SOIC-8 package only; 70 mA LDO output; no integrated LIN pull-up; requires external 1 kΩ pull-up for commander nodes | Lower current capability limits use to simpler sensor nodes; lacks AOI-optimized VSON packaging | Choose MC33664ELHR2 only if SOIC-8 footprint is mandatory and LDO load ≤70 mA; TLIN10285DRBRQ1 provides higher integration and smaller form factor |
Compared with TLIN1029DRBRQ1, TLIN10285DRBRQ1 trades wake-on-RXD and tighter DTO for cost efficiency and identical 125 mA LDO performance; versus MC33664ELHR2, it delivers 79% higher LDO current, eliminates external pull-up components, and enables automated optical inspection via VSON packaging.

FAQ
What LIN protocol versions does the TLIN10285DRBRQ1 support?
The TLIN10285DRBRQ1 supports LIN 2.2A per ISO/DIS 17987–4 and conforms to SAE J2602 recommended practice. It operates at standard LIN bit rates (10.4 kbps and 20 kbps) and meets all electrical parameters defined in those specifications, including duty cycle, threshold voltages, and bus timing. TLIN10285DRBRQ1 does not support LIN 2.0 or earlier legacy variants outside these standards.
Can the TLIN10285DRBRQ1 operate with a 3.3 V LDO output and still deliver 125 mA?
Yes - the TLIN10285DRBRQ1 delivers up to 125 mA from its integrated LDO at either 3.3 V or 5 V output, as confirmed in Section 7.6 of the datasheet. Dropout voltage is specified at 350–700 mV for the 3.3 V option, meaning VSUP must be ≥4.0 V to sustain 125 mA output. The VSON (8) package (DRB) enables this full current capability across both voltage options.
Does the TLIN10285DRBRQ1 require external pull-up resistors on the LIN bus?
No external pull-up is required for responder node applications, as TLIN10285DRBRQ1 integrates a 45 kΩ pull-up to VSUP on the LIN pin. Commander node applications require an external 1 kΩ pull-up plus series diode per SAE J2602, but TLIN10285DRBRQ1's internal pull-up remains active and does not conflict with this configuration.
How does the TLIN10285DRBRQ1 handle LIN bus dominant time-out (DTO) protection?
The TLIN10285DRBRQ1 implements hardware-enforced DTO protection with a nominal timeout of 34 ms (min 20 ms, max 80 ms). If TXD remains low beyond this window, the driver automatically disables to prevent bus lockup. This behavior is fully autonomous and requires no MCU intervention, ensuring system-level fault containment even during firmware hangs or communication errors.
Is the thermal pad on the TLIN10285DRBRQ1 VSON package required to be connected to ground?
Yes - the exposed thermal pad on the TLIN10285DRBRQ1 VSON-8 package must be soldered to the PCB ground plane. Section 6.1 of the datasheet explicitly states this requirement to achieve rated RθJA = 45.7 °C/W and prevent thermal shutdown under 125 mA load. Omitting pad connection degrades thermal performance and may cause premature device shutdown or parameter drift.
