GP7585B from HaloChip, 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 | GND | power_in | Chip ground; the datasheet absolute maximum for the VCC pin is 6 V and the recommended VCC operating voltage is 5 V. |
| 2 | GND | power_in | Chip ground, bonded together with pins 1 and 3; the datasheet gives no separate limit for this pin. |
| 3 | GND | power_in | Chip ground, bonded together with pins 1 and 2; the datasheet gives no separate limit for this pin. |
| 4 | VCC | power_in | Chip power supply that must be bypassed by a capacitor placed close to the pin; the datasheet gives VCC operating voltage 5 V, clamp voltage 6 V, UVLO(ON) 2.8 V and UVLO(OFF) 3.7 V. |
| 5 | SW | passive | Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended. |
| 6 | SW | passive | Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended. |
| 7 | SW | passive | Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended. |
| 8 | SW | passive | Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended. |
