TLIN1029DRQ1 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 output (open-drain) interface reporting state of the LIN bus voltage. Requires an external pull-up to VLOGIC (typ. 3.3V or 5V). Reports recessive/dominant state of LIN to the MCU. |
| 2 | EN | input | Enable input. High places the device in normal operation mode; low places the device in sleep mode. Also used to trigger local wakeup from sleep. |
| 3 | NC | unconnected | Not connected. Leave floating or tie per layout guidelines. |
| 4 | TXD | input | TXD input interface to control the state of the LIN output. Internally pulled to ground so an unconnected/failed TXD defaults to recessive on LIN. |
| 5 | GND | power_in | Device ground reference. |
| 6 | LIN | bidirectional | LIN bus single-wire transmitter and receiver. Tolerant to ±45V bus faults; typically decoupled with a 220 pF capacitor to GND per layout guidelines. In commander (master) mode a 1 kΩ pull-up to VSUP with series diode is required. |
| 7 | VSUP | power_in | Device supply voltage (connected to battery in series with an external reverse blocking diode). Recommended operating range 4V to 36V; absolute max 45V. |
| 8 | NC | unconnected | Not connected. |
