# CC6420SPB-FG

**Cross chip** · Brushless DC (BLDC) Motor Driver · SOP-8

CC6420SPB-FG from Cross chip, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PWM | input | PWM speed control input; accepts 0-0.4V (low) or 2.1-5.5V (high) with internal 10kΩ pull-up resistor. |
| 2 | FG/RD | output | Open-drain frequency generation or rotation detect output; 30mA current limit, maximum 18V withstand voltage, 0.2-0.5V saturation voltage. |
| 3 | OUT1 | output | H-bridge motor coil output 1; SVPWM modulated with 450mA continuous and 1000mA peak current capability. |
| 4 | VDD | power_in | Positive power supply input, operating range 3.5V to 18V, maximum absolute rating 21V with integrated voltage regulator. |
| 5 | OUT2 | output | H-bridge motor coil output 2; SVPWM modulated with 450mA continuous and 1000mA peak current capability. |
| 6 | GND | power_in | Ground reference for power supply and signal circuits; do not place components in series with GND path. |
| 7 | MINSP | input | Analog input for minimum speed setting; 0-2.5V range with 32-level resolution, or for analog speed regulation when PWM is grounded. |
| 8 | VREF | power_in | Reference voltage output (2.45-2.55V typical) with 5mA sink capability; requires >1μF capacitor to ground for system loop stability. |
