# GP7574D

**HaloChip** · Power Distribution Switches · SOP-8

GP7574D 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 pin; one of three GND pins on the SOP8 package. |
| 2 | GND | power_in | Chip ground pin; one of three GND pins on the SOP8 package. |
| 3 | GND | power_in | Chip ground pin; one of three GND pins on the SOP8 package. |
| 4 | VCC | power_in | Chip power supply pin, to be bypassed by a capacitor placed close to it; recommended VCC operating voltage is 5 V and the absolute maximum is 6 V, with UVLO turn-on at 2.8 V and turn-off at 3.7 V. |
| 5 | SW | passive | Drain of the internal power MOSFET; for the GP7574D the SW working voltage is limited to 40 V (recommended 4.7 to 36 V, with 10% derating). |
| 6 | SW | passive | Drain of the internal power MOSFET; for the GP7574D the SW working voltage is limited to 40 V (recommended 4.7 to 36 V, with 10% derating). |
| 7 | SW | passive | Drain of the internal power MOSFET; for the GP7574D the SW working voltage is limited to 40 V (recommended 4.7 to 36 V, with 10% derating). |
| 8 | SW | passive | Drain of the internal power MOSFET; for the GP7574D the SW working voltage is limited to 40 V (recommended 4.7 to 36 V, with 10% derating). |
