## CAD (KiCad official)

- Symbol: `DRV603PWR`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `drv603pwr-etched.step` / `drv603pwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `drv603pwr.step` / `drv603pwr.glb` are the bare package body.
