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 | AOUT1 | output | Winding A output. Connect to stepper motor winding. |+| 2 | AOUT2 | output | Winding A output. Connect to stepper motor winding. |+| 3 | BOUT2 | output | Winding B output. Connect to stepper motor winding. |+| 4 | BOUT1 | output | Winding B output. Connect to stepper motor winding. |+| 5 | GND | power_in | Device ground. Connect to system ground. |+| 6 | 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. |+| 7 | VREF | power_in | Current set reference input. Maximum value 3 V; DVDD can be used to provide VREF through a resistor divider. |+| 8 | M0 | input | Microstepping mode-setting pin. Sets the step mode with internal pulldown resistor. |+| 9 | DECAY/TOFF | input | Decay-mode and off-time setting pin. See Section 7.3.5 for details. |+| 10 | M1 | input | Microstepping mode-setting pin. Sets the step mode with internal pulldown resistor. |+| 11 | STEP | input | Step input. A rising edge causes the indexer to advance one step with internal pulldown resistor. |+| 12 | DIR | input | Direction input. Logic level sets the direction of stepping with internal pulldown resistor. |+| 13 | EN/nFAULT | bidirectional | Logic low to disable device outputs; logic high to enable. Also used for fault indication output, pulled logic low in fault condition. |+| 14 | nSLEEP | input | Sleep mode input. Logic high to enable device; logic low to enter low-power sleep mode with internal pulldown resistor. An nSLEEP low pulse clears faults. |+| 15 | VM | power_in | Motor power supply. Connect to motor supply voltage and bypass to PGND with a 0.01-µF ceramic capacitor plus a bulk capacitor rated for VM. |+| 16 | PGND | power_in | Power ground. Connect to system ground. |+| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WQFN-16-EP(3x3) |+| Category | Motor Driver ICs |+| Pins | 17 |++## CAD (KiCad official)++- Symbol: `DRV8428RTER`+- Footprint: `Package_DFN_QFN:QFN-16-1EP_3x3mm_P0.5mm_EP1.7x1.7mm`+- 3D model: WQFN-16-EP(3x3) (KiCad packages3D, STEP)+- 3D model files: `drv8428rter-etched.step` / `drv8428rter-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `drv8428rter.step` / `drv8428rter.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/drv8428) (49 pp, sha256 `e7adba1f405903be`, retrieved 2026-10-01, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
