# GP8616F

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

GP8616F 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 | FB | input | Feedback voltage input for constant-voltage regulation, with a 2 V reference (1.975 to 2.025 V), an FB overvoltage protection level of 2.6 V and an FB undervoltage protection level of 1.2 V. |
| 2 | GND | power_in | Chip ground, which is also the return for the current-sense resistor connected between CS and GND. |
| 3 | VCC | power_in | Chip supply pin that should be bypassed with a capacitor placed close to VCC and GND; absolute maximum is -0.3 to 25 V, with a start-up voltage of 13.5 to 15.5 V and an undervoltage lockout of 4.1 to 5.1 V. |
| 4 | CS | input | Current-sense input in which the sense resistor is connected between CS and GND, with a peak-current comparator threshold of 500 mV (490 to 510 mV) and an absolute maximum of -0.3 to 6 V. |
| 5 | C | passive | Collector of the internal power transistor; increase the copper area on the C pins to improve heat dissipation, with C-B breakdown of 800 V and C-E breakdown of 450 V for the GP8616F. |
| 6 | C | passive | Collector of the internal power transistor; increase the copper area on the C pins to improve heat dissipation, with C-B breakdown of 800 V and C-E breakdown of 450 V for the GP8616F. |
| 7 | C | passive | Collector of the internal power transistor; increase the copper area on the C pins to improve heat dissipation, with C-B breakdown of 800 V and C-E breakdown of 450 V for the GP8616F. |
| 8 | C | passive | Collector of the internal power transistor; increase the copper area on the C pins to improve heat dissipation, with C-B breakdown of 800 V and C-E breakdown of 450 V for the GP8616F. |
