LDR6328 from Legendary, 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 | VSS | power_in | Chip ground. |
| 2 | EPP/BPP | input | Pulled low selects EPP power supply, left floating selects BPP power supply; floating also makes the sink request 9V first (else 5V), while an external pull-down to ground requests 12V, 9V, 5V in priority order. |
| 3 | EN_D+ | bidirectional | Used to control the output voltage of the USB port D+ line. |
| 4 | ADC_D- | bidirectional | Used to control the output voltage of the USB port D- line. |
| 5 | CC2 | bidirectional | CC2 channel level detection for the C1 port, used for USB PD communication. |
| 6 | CC1 | bidirectional | CC1 channel level detection for the C1 port, used for USB PD communication. |
| 7 | PDLDO/VREF | bidirectional | External capacitor connection for the USB PD communication LDO, also reserved for VBUS voltage detection. |
| 8 | VDD | power_in | Chip power supply, recommended 3.3V to 5V, absolute maximum -0.3V to 6.0V. |
