If you have only one PWM signal available:

–

To have gate output in phase with input command: PWM on IN+ and IN- = GND

–

To have gate output out of phase with input command: PWM on IN- and

IN+ = VDD

Connection to STEVAL-PCC009V2 interface board

The EVALSTGAP1AS shall be connected to the interface board and the following steps

performed:

1.

Connect the interface board to the PC through the USB cable: the red LED (POWER -

D2) turns on

2.

Connect the interface board 10-pin connector to the EVALSTGAP1AS J4 connector

through the 10-pin flat cable

The DIAG1 red LED (DL2) on the EVALSTGAP1AS turns-on

3.

Connect the power supply to VH of the EVALSTGAP1AS (J2 connector) and turn it on

4.

Start the EVALSTGAP1AS evaluation software

5.

Click the icon 'Connect' on the top left side of the GUI window to establish a connection

between the EVALSTGAP1AS and interface boards (see Figure 9)

The DIAG1 LED (DL2) on the EVALSTGAP1AS is switched off

6.

Press the 'Refresh' button and verify all fault lights are off. If OK jump to the next point,

otherwise two options are available to clear the faults and make the device operative:

a)

Perform a double transition on SD (high => low => high) clicking on the SD button

b)

Perform a status reset clicking on the 'Reset' button and after set the SD button to

'High'

7.

Set the SD button to 'High'

8.

Connect IN- to GND and applying the PWM on IN+, the device outputs will follow the

input signal

In order to read the device status, use the 'Refresh' button to update the status indicators

according to driver's status registers.

To customize the device parameters and functions open the 'STGAP1AS configuration'

panel pushing the relative toolbar icon (refer to Figure 9).
