Hi,
Am using EiceDRIVER™ 1ED38x0Mc12M development board for my project.
Please give some ideas how to start.
I have configured the gate driver through I2C using my microcontroller.
Output is not coming..
Please help me to get output.
Thanks in advance

Hi,
Thank you for posting at Infineon community.
Please share your board layout to start troubleshooting.

Hi,
Thank you for sharing the schematic. Looks like you have not done any changes in schematics. The problem is from configuration side I believe. Please let me know what all configurations you did before starting .

Hi,
I have configured the registers as below mentioned
Input pin filter time for RDYC, IN, FLT & I2C – 0x03H
- Configured as 100ns for IN, RDYC, FLT and 50ns for I2C pins
- Value loaded to this is 0x0H
Fault Clear method – 0x04H
- Configured as by RDYC pin
- so no need to configure self-clear time we kept let it be
- Value loaded to this register is 0x0H
Input and output configuration recovery modes – 0x05H
- Configured as Restore from input side and recover from output side
- Value loaded to this register is 0x3H
UVLO threshold level for VCC2 and VEE2 – 0x06H
- Configured as VCC2 threshold level for MOSFET (we have given +15V)
- Configured as VEE2 level as -5 negative supply (we have given -5V)
- Value loaded to this register is 0x5H
VCC2 UVLO soft enable and threshold level – 0x07H
- Soft enabled
- 9.5V selected as Threshold level
- Value loaded to this register is 0x10H
VEE2 UVLO soft enable and threshold level – 0x08H
- Soft enabled
- -5V selected as threshold level
- Value loaded to this register is 0x13H
ADC enable and compare polarity – 0x09H
- Clamp pin voltage limit compare is disabled
- Configured as 0 fault event
- Clamp pin voltage measurement is disabled
- Supply voltage measurement (VCC2, VEE2, GND2) is enabled.
- Value loaded to this register is 0x04
Clamp pin voltage compare limit – 0x0AH
- Configured as 0
- Value loaded to this register is 0x0H
Over Temperature warning level – 0x0BH
- Configured to trigger fault
- 95° C selected temperature threshold level
- Value loaded to this register is 0xFH
DESAT disable and DESAT threshold level – 0x0CH
- DESAT enabled
- DESAT voltage threshold level is selected as 9.18V
- Value loaded to this register is 0x1FH
Clear event counter register – 0x1DH
- Configured to clear all the events
- Value loaded to this register is 0x1FH
Register configuration lock – 0x1CH
- Configured write protection
- Value loaded to this register is 0x1H
Please check and reply
I did't configure the registers other than this

Hi,
Thanks for your reply.
We have given +15V to the Evaluation board.
We don't have 1ED38x0DCT microcontroller board.
Instead we are suing TMS320F28379D controlsitck from TI.
We are configuring the gate driver through I2C using that TI controller mentioned above.
If possible send me sample code to configure the parameters, it will be helpful.
Thanks

Hi,
Sorry, we cant not give sample code since you are using TI microcontroller.

As per the reference manual we have configured the 1ED38x0Mx12M.
But we are not getting the PWM output.
Gate driver is not going to normal operating state.
we had read all the status register and fault registers and there is no fault internally.
How to resolve this and how to make the gate driver to ready state.
