APPENDIX - EVALUATION BOARDS
4.1 PractiSPIN
PractiSPIN is an evaluation and demonstration system that can be used with the PowerSPIN family (L62XX) of
devices. A Graphical User Interface (GUI) (see Figure 37) program runs on an IBM-PC under windows and com-
municates with a common ST7 based interface board (see Figure 38) through the RS232 serial port. The ST7
interface board connects to a device specific evaluation board (target board) via a standard 34 pin ribbon cable
interface.
Depending on the target device the PractiSPIN can drive a stepper motor, 1 or 2 DC motors or a brushless DC
(BLDC) motor, operating significant parameters such as SPEED, CURRENT, VOLTAGE, DIRECTION, ACCEL-
ERATION and DECELERATION RATES from a user friendly graphic interface, and programming a sequence
of movements.
The software also allows evaluating the power dissipated by the selected device and, for a given package and
dissipating copper area on the PCB, estimates the device's junction temperature.
