DRV10866DSCR from Texas Instruments, in a WSON-10-EP(3x3). 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 | FG | output | Open-drain frequency generator output that gives one electrical cycle per period when FGS is tied to GND, or half that frequency (1/2FG) when FGS is tied to VCC, and needs an external pullup when connected to a system. |
| 2 | COM | input | Motor common terminal input, with recommended operating voltage range of -0.1 V to 5.5 V. |
| 3 | VCC | power_in | Input voltage for motor and chip supply, with recommended supply range of 1.65 V to 5.5 V, and an internal clamp that limits VCC during lock protection and standby. |
| 4 | U | output | Phase U motor drive output, with recommended operating voltage range of -0.7 V to 6.5 V. |
| 5 | GND | power_in | Ground pin, connected to the thermal pad. |
| 6 | W | output | Phase W motor drive output, with recommended operating voltage range of -0.7 V to 6.5 V. |
| 7 | V | power_in | Phase V motor drive output, with recommended operating voltage range of -0.7 V to 6.5 V. |
| 8 | FGS | input | FG and 1/2FG select pin, latched upon wake-up from the PWM pin, with FGS tied to GND selecting FG and tied to VCC selecting 1/2FG, and a recommended range of -0.1 V to 5.5 V. |
| 9 | CS | input | Overcurrent threshold setup pin where the overcurrent limit is I(mA) = 3120/RCS(kΩ) over the valid range 300 mA < ILIMIT < 850 mA, and shorting CS to ground disables overcurrent protection. |
| 10 | PWM | input | PWM speed input for 15 kHz to 50 kHz, where the device enters low-power standby after PWM stays low for up to 500 µs and wakes on the rising edge. |
| 11 | GND | power_in | Exposed thermal pad connected to ground that must be soldered to the printed circuit board for optimal thermal and mechanical performance. |
