TLIN2029DRQ1 from Texas Instruments, in a SOIC-8. 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 | RXD | output | RXD open-drain output that reports LIN bus voltage state with maximum low voltage of 0.6V at output current of 1.5mA. |
| 2 | EN | input | Enable input that places device in normal mode when high (≥2V) and sleep mode when low (≤0.8V). |
| 3 | NC | unconnected | Not connected. |
| 4 | TXD | input | TXD input that controls LIN transmitter output state with internal pull-down to ground; high (≥2V) drives recessive, low (≤0.8V) drives dominant. |
| 5 | GND | power_in | Ground reference connection; device operates with ground offset if VSUP ≥ 4V. |
| 6 | LIN | bidirectional | Single-wire LIN bus transceiver with ±60V transient protection and ±45V fault protection; dominant output ≤ 0.2×VSUP or 1.2V, recessive output ≥ 0.85×VSUP or 3V. |
| 7 | VSUP | power_in | Device power supply input with nominal range 4V to 48V; requires external blocking diode in series connection to battery. |
| 8 | NC | unconnected | Not connected. |
