Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VSUP | power_in | Device high-voltage supply input, connected to the automotive battery in series with an external reverse-blocking diode. Operational supply 5.5 V to 36 V; nominal 5.5 V to 28 V; absolute maximum -0.3 V to 42 V. Requires a 100 nF supply-bypass capacitor. |+| 2 | EN | input | Enable input (digital, high-voltage tolerant). Drives device mode transitions: EN = VCC selects normal mode, EN = 0 V selects standby/sleep modes. Logic input range 0 V to 5.25 V (5 V logic) / 3.465 V (3.3 V logic); absolute max -0.3 V to 6 V. |+| 3 | GND | power_in | Device ground reference. When the thermal pad is present (DRB/DDA packages), it must be soldered to the ground plane; this D-package variant has no thermal pad. |+| 4 | LIN | bidirectional | LIN bus single-wire transmitter and receiver terminal (high-voltage I/O). Supports LIN 2.2A / ISO/DIS 17987-4 signaling with ±58 V bus fault protection and slew-shaped output for reduced EME. Bus operating range 0 V to 28 V. |+| 5 | RXD | output | RXD open-drain output that reports the state of the LIN bus voltage to the microcontroller UART receive pin. Requires an external pull-up to VCC (2 kΩ to 10 kΩ typical); VOL ≤ 0.2 V at IOL = 1.5 mA. Reset/RXD open-drain current rated ±5 mA absolute maximum. |+| 6 | TXD | input | TXD digital input from the microcontroller UART transmit pin that controls the state of the LIN bus output driver (low on TXD = dominant on LIN). Logic input range 0 V to 5.25 V (5 V logic) / 3.465 V (3.3 V logic); dominant time-out protection is provided to prevent bus lock-up. |+| 7 | nRST | output | Active-low reset output (open-drain style, VnRST rated -0.3 V to VCC + 0.3 V). Asserts low on VCC undervoltage or thermal-shutdown events to hold the host microcontroller in reset; deasserts after VCC returns above the UV rising threshold. |+| 8 | VCC | power_out | Regulated output from the integrated LDO. For the TLIN10285 (5 V) variant in the D package: 5 V ± 2 % up to 70 mA of load (ICCOUT). Requires 1.5 µF (20 µA to full load) or 10 µF (no load to full load) bypass with ESR 0.001 Ω to 2 Ω. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++- `TLIN10285DRQ1D`+- `TLIN10285DRQ1DR`+- `TLIN10285DRQ1DRB`+- `TLIN10285DRQ1DRBR`+- `TLIN10285DRQ1DDA`+- `TLIN10285DRQ1DDAR`++## CAD (KiCad official)++- Symbol: `TLIN10285DRQ1`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/tlin10285drq1-datasheet.pdf) (54 pp, sha256 `e0f338741b4b46aa`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
