Size optimization design procedure
This demo board implements a general solution to drive a low voltage DC brush motor. The
application is optimized for cordless hand tools (drill, saw, screwdriver).
The size is small enough to be inserted directly in the tool
To minimize the size of the board:
●
●
●
●
Following this procedure, the optimal design achieved is approximately 20x15 mm.
The demo board is implemented only on the top to reduce the manufacturing cost.
The ICC connector is not needed in the manufacturing process either because the
microcontroller can be already programmed before assembling.
The potentiometer emulates the push button of the cordless drill. (To be replaced by the
potentiometer/on-off switch on the tool)
The Power MOSFET and diode can be mounted near the motor where the air flux cools
them down.
The UltraLite is available in DFN8 package (Less than 16 mm
