DRV8873-Q1: IPROPI vs. temperature

Part Number: DRV8873-Q1
Other Parts Discussed in Thread: DRV8873, DRV8243-Q1

Dear team,

can we provide some data regarding IPROPI variation vs. temperature for DRV8873 ?

Something similar to what we provide for DRV8243-Q1, see datasheet extract below.

Thanks a lot!

Best regards,

PA

    Hi Pial,

    We don't have this specific data. The datasheet provides ITRIP current vs temperature characteristic waveforms. This is not exactly what you are asking for but it provides how the ITRIP current changes through temperature. The ITRIP current is inversely proportional to the A_IPROPI gain so it follows the waveform you attached in your post.

    Regards,

    Pablo
