Pin Assignment
Here are the pinouts for the DRV8312/32:
• DRV8312: 44-pin TSSOP power pad down DDW package. This package contains a thermal pad that is
located on the bottom side of the device for dissipating heat through PCB.
• DRV8332: 36-pin PSOP3 DKD package. This package contains a thick heat slug that is located on the top
side of the device for dissipating heat through heatsink.
