TMI8230

TMI · Motor Driver ICs · DFN-8-EP(2x2)

TMI8230 from TMI, in a DFN-8-EP(2x2). 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 driver power supply (1.8V to 11V); connect a 0.1μF ceramic bypass capacitor and a 47μF bulk capacitor to GND.
2 OUT1 output H-bridge motor driver output 1.
3 OUT2 output H-bridge motor driver output 2.
4 GND power_in Ground pin.
5 IN2 input Control logic input 2 with internal pulldown (100kΩ typical).
6 IN1 input Control logic input 1 with internal pulldown (100kΩ typical).
7 EN input Chip enable input; logic low puts the device in low-power sleep mode, logic high gives normal operation, with an internal pulldown resistor to GND.
8 VCC power_in Logic input power supply (1.8V to 7V); connect a 0.1μF ceramic bypass capacitor to GND.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TMI8230
  • Footprint: Package_DFN_QFN:DFN-8-1EP_2x2mm_P0.5mm_EP0.6x1.2mm
  • 3D model: DFN-8-EP(2x2) (KiCad packages3D, STEP)
  • 3D model files: tmi8230-etched.step / tmi8230-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi8230.step / tmi8230.glb are the bare package body.
