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.
