Hi,

We plan to use TLE9180D-31QK to drive BLDC motor. We would like to know  the maximum output voltage of VO1.

Is VRO settable by reference buffer through SPI?  

What should be the typical values of CISPx, CDIFF and CISNx if our switching frequency is 15kHz.

Also would like to know how the bootstrap capacitor value is calculated for CBSx.

Awaiting your reply.

Thanks  and Regards

Alok

Hii @Alok-86 

Yes. VRO is settable through SPI. You may refer to table 14 and 15 of the datasheet. Additionally, section 15.1.2.4 also discusses the VRO settings.

Is there a user manual and application circuit note for this IC? if yes, could you please share the link so that we can download.

We are referring to following datasheet

https://www.infineon.com/dgdl/Infineon-TLE9180D-31QK-ProductInformation-v01_00-EN.pdf?fileId=5546d46...

 

Please let us know if there is any other datasheet as table 14 and 15 and section 15.1.2.4 are not available in the datasheet.
