Figure 36. PractiSPIN ST7 Evaluation Board

5.2 EVAL6205N

An evaluation board has been produced to help the evaluation of the device in PowerDIP package. It imple-

ments a typical application with several added components. Figure 38 shows the electrical schematic of the

board; in the table below the part list is reported.

The Evaluation Board provides external connectors for the supply voltage, an external 5V reference for the logic

inputs, four outputs for the motor and a 34-pin connector to control the main functions of the board through an

external µC board or the PractiSPIN tool. The board also accommodates the L6506 PWM current controller.

R23 sets the PWM operating frequency. If the L6506 does not need to be used, simply connect the two VREF

inputs to a voltage high enough to keep current control inactive.

The PractiSPIN tool is composed of a graphic interface software running on a PC that connects with the hard-

ware based on the ST7 µC, which contains an upgradeable firmware. This tool allows a fast and easy evaluation

of the PowerSPIN family devices, giving the ability of driving DC, BLDC and Stepper motors, depending on the

target device. The PractiSPIN connected to the EVAL6205N can drive DC motors and inductive loads, allowing

output voltage and current settings

The PC-software also provides a Power Dissipation and Thermal Analysis section, intended to help a fast eval-

uation of the device, package and dissipating copper area required by the user’s application, and to be a good

starting point designing an application (from the power dissipation and thermal point of view).
