EVAL6235PD

L6235 three-phase brushless DC motor driver demonstration board

Features

Description

The EVAL6235PD demonstration board is a fully

integrated DMOS three-phase brushless DC

motor driver.

Used in conjunction with the EVALPRACTISPIN

interface board and practiSPIN software, the

board provides an evaluation platform to test the

features of the L6235 device. In particular, the

board provides a means to evaluate the power

dissipation performance of the IC in the PowerSO

package.

An example of speed loop is implemented. The

speed information is obtained by analog

integration of the TACHO output. Fine tuning of

external components is needed to fit application

requirements.

The board is designed with a large GND area to

minimize noise and optimize power dissipation.
