DRV8428PWPR
Texas Instruments · Stepper Motor Driver · HTSSOP-16
DRV8428PWPR from Texas Instruments, in a HTSSOP-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 | VM | power_in | Power supply connected to the motor supply voltage; bypass to PGND with a 0.01-µF ceramic capacitor plus a bulk capacitor rated for VM. |
| 2 | PGND | power_in | Power ground; connect to system ground. |
| 3 | AOUT1 | output | Output winding A output; connect to stepper motor winding. |
| 4 | AOUT2 | output | Output winding A output; connect to stepper motor winding. |
| 5 | BOUT2 | output | Output winding B output; connect to stepper motor winding. |
| 6 | BOUT1 | output | Output winding B output; connect to stepper motor winding. |
| 7 | GND | power_in | Device ground; connect to system ground. |
| 8 | DVDD | power_in | Logic supply voltage; connect a X7R, 0.47-µF to 1-µF, 6.3-V or 10-V rated ceramic capacitor to GND. |
| 9 | VREF | power_in | Current set reference input; maximum value 3 V, and DVDD can be used to provide VREF through a resistor divider. |
| 10 | M0 | input | Microstepping mode-setting pin that sets the step mode; internal pulldown resistor. |
| 11 | DECAY/TOFF | input | Decay-mode and off-time setting pin; see Section 7.3.5 of the datasheet for details. |
| 12 | M1 | input | Microstepping mode-setting pin that sets the step mode; internal pulldown resistor. |
| 13 | STEP | input | Step input; a rising edge causes the indexer to advance one step; internal pulldown resistor. |
| 14 | DIR | input | Direction input; the logic level sets the direction of stepping; internal pulldown resistor. |
| 15 | EN/nFAULT | bidirectional | Logic low disables device outputs and logic high enables them; also used as fault indication, pulled logic low in a fault condition. |
| 16 | nSLEEP | input | Sleep mode input; logic high enables the device and logic low enters low-power sleep mode; internal pulldown resistor; an nSLEEP low pulse clears faults. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
