# TLIN1029DRBRQ1

**Texas Instruments** · LIN Transceivers · HVSON-8-EP(3x3)

TLIN1029DRBRQ1 from Texas Instruments, in a HVSON-8-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RXD | output | RXD output (open-drain) interface reporting state of LIN bus voltage. |
| 2 | EN | input | Enable input - high puts the device in normal operation mode and low puts the device in sleep mode. |
| 3 | NC | unconnected | Not connected. |
| 4 | TXD | input | TXD input interface to control state of LIN output - internally pulled to ground. |
| 5 | GND | power_in | Ground. |
| 6 | LIN | bidirectional | LIN bus single-wire transmitter and receiver. |
| 7 | VSUP | power_in | Device supply voltage (connected to battery in series with external reverse blocking diode). |
| 8 | NC | unconnected | Not connected. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TLIN1029DRBRQ1`
- Footprint: `Package_SON:HVSON-8-1EP_3x3mm_P0.65mm_EP1.6x2.4mm`
- 3D model: HVSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tlin1029drbrq1-etched.step` / `tlin1029drbrq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tlin1029drbrq1.step` / `tlin1029drbrq1.glb` are the bare package body.
