b. For alternate configurations and setup details, see
"Signal related jumpers and configuration"
, and
4. Start SPIGEN application software on PC. Connect USB cable from PC to USBKL25Z
port on KL25Z micro board. A successful connection results in a connection
successful pop-up (reading "SPI dongle is connected") on the PC with SPIGEN
application running.
a. KL25Z micro shipped with proper firmware is already flashed. See
"Installation and use of software tools"
5. Next supply 12 V DC power to low voltage domain of evaluation board (12 V DC
to VSUP connection point and grounding to GND1 connection point on low voltage
domain).
6. Check high-side and low-side driver domain regulated voltage level by checking
VCCH and VCCL test points for ~17 V DC with respect to grounding to points GNDH
and GNDL in each domain respectively.
a. If voltage level on VCCH and VCCL are low adjust R20 potentiometer for proper
level as shown in
7. With proper PC interface connection and voltage levels, SPI communication can be
conducted with GD3100 devices over SPIGen as described in
SPIGEN graphical user interface"
. See GD3100 data sheet for additional details.
a. Selecting SPI0 communicates with low-side gate drive device and SPI1
communicates with high-side gate drive device (see
).
8. Apply PWM signals to each gate drive. Gate drive output can be observed on high-
side and low-side driver devices with test points (GH, GL), or 50 Ω port (MMCX GATE
H/L).
a. To receive PWM as provided by the KL25Z, see
Section 4.6.1 "Configuring the
translator for KL25Z-controlled PWM"
b. To set up for external PWM control, see
Section 4.6.2 "Configuring the translator
. Apply a control signal with an external function
generator.
9. For double pulse and short-circuit testing with an IGBT and inductive load, use
the "Pulse test" view as part of the SPIGen GUI. Set parameterized pulse widths
commanded by the KL25Z.
a. For short-circuit testing, PWMHSEL and PWMLSEL must be configured so as to
bypass dead time control (see
Section 4.4.4.2 "Configuring dead time application
).
6 Installation and use of software tools
Software for FRDMGD3100HBIEVM is distributed with the SPIGen GUI tool (available on
). Necessary firmware comes pre-installed on the FRDM-KL25Z with the kit.
Even if the user intends to test under other software or PWM, it is recommended the user
install this software below as a backup or in help debugging.
