GC1267F from SX-globalchip, in a SSOP-16. 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 | OUT2P | output | High side output 2 of the single-phase full-wave bridge. |
| 2 | OUT2N | output | Low side output 2 of the single-phase full-wave bridge. |
| 3 | Vcc | power_in | Power supply pin; use a stabilization capacitor of 1µF or more on the signal side and connect VCC and GND with a thick, shortest pattern. |
| 4 | SENSE | bidirectional | Current limiting detection pin; when its voltage exceeds 0.2V the current is limited and operation enters lower regeneration mode, and it must be connected to GND when not used. |
| 5 | RMI | input | Minimum speed setting pin with a 0 to 5 V input range; pull up to 5VREG when not used, and insert a current limiting resistor if driven from an external supply. |
| 6 | VTH | input | Speed control pin with a 0 to 5 V input range; connect to GND for full speed when not used, and use 20kHz to 100kHz pulse input (20kHz to 50kHz recommended) with a current limiting resistor. |
| 7 | CPWM | bidirectional | Pin for the capacitor that sets the PWM basic frequency, where CP = 220pF gives 30kHz; the capacitor must be connected even when speed control is not used. |
| 8 | FG | output | Rotation speed detection open collector output that follows the phase changeover; keep open when not used, with a withstand voltage of 19 V and maximum output current of 10 mA. |
| 9 | IN- | input | Negative Hall signal input with differential sensitivity of ±10 to ±20 mV including offset and hysteresis. |
| 10 | IN+ | input | Positive Hall signal input with a common-phase input voltage range of 0.2 to 3 V. |
| 11 | CT | bidirectional | Lock detection capacitor pin where locking occurs at 3.0V and unlocking at 1.1V; connect to GND when locking is not used. |
| 12 | S-S | bidirectional | Soft-start setting capacitor pin connected between 5VREG and S-S with a recommended capacitor of 0.1µF to 1µF; connect to GND when not used. |
| 13 | 5VREG | bidirectional | Internal 5V reference output, 4.80 to 5.10 V at 5 mA, with a maximum output current of 20 mA. |
| 14 | SGND | power_in | Ground pin connected to the control circuit power supply system. |
| 15 | OUT1N | output | Low side output 1 of the single-phase full-wave bridge. |
| 16 | OUT1P | output | High side output 1 of the single-phase full-wave bridge. |
