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

GP8691H 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, with the bypass capacitor placed right next to the VCC and GND pins; the datasheet gives VCC absolute maximum -0.3 to 35 V, start-up threshold 13.5-15.5 V, UVLO 4.1-5.1 V and overvoltage protection 29-33 V. |
| 2 | GND | power_in | Chip ground; the power ground of the current-sense resistor should be routed short and separately from the chip ground and other small-signal grounds to the bulk capacitor ground. |
| 3 | FB | input | Feedback voltage input for constant-voltage regulation, with the FB divider resistors kept close to the pin; the datasheet gives an absolute maximum of -0.3 to 6 V and an FB reference of 1.975-2.025 V (typ. 2 V). |
| 4 | CS | input | Current-sense input, with the sense resistor connected between CS and GND, which sets the peak current as I_P_PK = 500/R_CS (mA) and includes a 500 ns leading-edge blanking time; the absolute maximum is -0.3 to 6 V. |
| 5 | C | output | Collector of the internal power composite transistor; the datasheet specifies GP8691H C-B breakdown of 700 V min at IC=0.1 mA, C-E breakdown of 400 V min, and C-E saturation current of 1.2 A, and recommends enlarging the copper area on the C pins for heat dissipation. |
| 6 | C | output | Collector of the internal power composite transistor, tied together with pins 5, 7 and 8; the datasheet specifies GP8691H C-B breakdown of 700 V min at IC=0.1 mA, C-E breakdown of 400 V min, and C-E saturation current of 1.2 A, and recommends enlarging the copper area on the C pins for heat dissipation. |
| 7 | C | output | Collector of the internal power composite transistor, tied together with pins 5, 6 and 8; the datasheet specifies GP8691H C-B breakdown of 700 V min at IC=0.1 mA, C-E breakdown of 400 V min, and C-E saturation current of 1.2 A, and recommends enlarging the copper area on the C pins for heat dissipation. |
| 8 | C | output | Collector of the internal power composite transistor, tied together with pins 5, 6 and 7; the datasheet specifies GP8691H C-B breakdown of 700 V min at IC=0.1 mA, C-E breakdown of 400 V min, and C-E saturation current of 1.2 A, and recommends enlarging the copper area on the C pins for heat dissipation. |
