XL33290 from XINLUDA, in a SOP-8. 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 | VBB | power_in | Battery power input supplied through an external resistor and diode, specified for 8.0 V to 18 V. |
| 2 | NC | unconnected | Not to be connected, and NC pins are not guaranteed to be open circuits. |
| 3 | GND | power_in | Common signal and power return. |
| 4 | ISO | bidirectional | ISO K line bus connection, protected against shorts to ground and overtemperature. |
| 5 | TX | input | Logic level input for data to be transmitted on the bus, with an internal pull-up to VDD. |
| 6 | RX | output | Logic output of data received from the bus. |
| 7 | VDD | power_in | Logic power supply input, specified for 4.75 V to 5.25 V. |
| 8 | CEN | input | Chip enable, where logic 1 is the active state and logic 0 is the sleep state, with an internal pull-down. |
