DRV10974PWPR from Texas Instruments, in a HTSSOP-16-EP. 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 | ADV | input | Selects the applied lead angle through a 1/8-W resistor, and leaving the pin open gives the longest lead angle; the setting is read at power up. |
| 2 | FR | input | Direction control where FR = 0 gives U→V→W and FR = 1 gives U→W→V, with the value latched on exit of low-power mode and an internal pulldown. |
| 3 | FG | output | Open-drain motor speed-feedback output with internal pullup to V3P3, and a pullup resistor is needed to limit current if the pullup voltage is higher than V3P3. |
| 4 | PWM | input | Motor speed-control input with auto detection of analog or digital mode and an internal pullup to 2.2 V. |
| 5 | V1P8 | power_out | LDO regulator output for internal operation that requires a 1-µF, 6.3-V ceramic capacitor tied to GND and can supply a maximum of 3 mA to an external load. |
| 6 | RMP | input | Acceleration ramp-rate control set by a 1/8-W resistor to GND, and leaving the pin open gives the slowest acceleration rate. |
| 7 | GND | power_in | Digital and analog ground. |
| 8 | CS | input | Selects the current limit through a 1/8-W resistor, and leaving the pin open gives the highest current limit. |
| 9 | NC | unconnected | No internal connection. |
| 10 | PGND | power_in | Power ground connection for motor power. |
| 11 | U | bidirectional | Motor phase U connection. |
| 12 | V | power_in | Motor phase V connection. |
| 13 | W | bidirectional | Motor phase W connection. |
| 14 | VCC | power_in | Power-supply connection that requires a 10-µF, 25-V ceramic capacitor tied to GND. |
| 15 | VCP | output | Charge-pump output that requires a 100-nF, 10-V ceramic capacitor tied to VCC. |
| 16 | GND | power_in | Digital and analog ground. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
