DRV8839DSSR

Texas Instruments · Stepper Motor Driver · WSON-12-EP(2x3)

DRV8839DSSR from Texas Instruments, in a WSON-12-EP(2x3). 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 Motor supply voltage input (0V to 11V); bypass to ground with 0.1-μF, 16-V ceramic capacitor.
2 VM power_in Motor supply voltage input (0V to 11V); bypass to ground with 0.1-μF, 16-V ceramic capacitor.
3 OUT1 tri_state H-bridge output 1 for motor winding; tri-state output controlled by EN1 (enable) and IN1 (direction/state).
4 OUT2 tri_state H-bridge output 2; tri-state output controlled by EN2 (enable) and IN2 (direction/state).
5 GND power_in Device ground connection.
6 GND power_in Device ground connection.
7 EN2 input Logic input to enable H-bridge 2 output; logic high enables OUT2, internal pulldown resistor.
8 IN2 input Logic input controlling H-bridge 2 state; internal pulldown resistor.
9 EN1 input Logic input to enable H-bridge 1 output; logic high enables OUT1, internal pulldown resistor.
10 IN1 input Logic input controlling H-bridge 1 state; internal pulldown resistor.
11 nSLEEP input Sleep mode input; logic low enters low-power sleep mode, logic high for normal operation, internal pulldown resistor.
12 VCC power_in Logic supply voltage input (1.8V to 7V); bypass to ground with 0.1-μF, 6.3-V ceramic capacitor.
13 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: DRV8839DSSR
  • Footprint: Package_SON:WSON-12-1EP_3x2mm_P0.5mm_EP1x2.65
  • 3D model: WSON-12-EP(2x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.75 mm nominal WSON height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: drv8839dssr-etched.step / drv8839dssr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); drv8839dssr.step / drv8839dssr.glb are the bare package body.
