# GP8615F

**HaloChip** · AC-DC Controllers And Regulators · SOP-8

GP8615F 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 | VCC | power_in | Chip supply pin that should have a bypass capacitor placed close to the VCC and GND pins; the datasheet gives an absolute maximum of -0.3 to 25 V, a startup threshold of 13.5 to 15.5 V, an undervoltage threshold of 4.1 to 5.1 V and an overvoltage protection value of 22 to 26 V. |
| 2 | GND | power_in | Chip ground pin, which should be routed separately from the power-stage current-sense return as described in the PCB layout guidance. |
| 3 | FB | input | Feedback voltage input with an absolute maximum of -0.3 to 6 V, a reference of 2 V (1.975 to 2.025 V), an overvoltage protection level of 2.6 V and an undervoltage protection level of 1.2 V. |
| 4 | CS | input | Current-sense input where the sense resistor is connected between CS and GND, with an absolute maximum of -0.3 to 6 V and a constant-current detection threshold of 490 to 510 mV. |
| 5 | C | output | Collector of the internal power transistor, with a collector maximum DC current of 2.5 A, a pulsed current of 5 A, and C-B and C-E breakdown voltages of 700 V and 400 V respectively; the datasheet recommends a large copper area on this pin for heat dissipation. |
| 6 | C | output | Collector of the internal power transistor, with the same ratings as pin 5 (2.5 A DC, 5 A pulsed, 700 V C-B and 400 V C-E); it is internally the same node as the other C pins. |
| 7 | C | output | Collector of the internal power transistor, with the same ratings as pin 5 (2.5 A DC, 5 A pulsed, 700 V C-B and 400 V C-E); it is internally the same node as the other C pins. |
| 8 | C | output | Collector of the internal power transistor, with the same ratings as pin 5 (2.5 A DC, 5 A pulsed, 700 V C-B and 400 V C-E); it is internally the same node as the other C pins. |
