Hello expert,
I have question for DRV8312's BST cap.
In the datasheet p26 schematics example used 100V 100nF MLCC.
However, we'd like to use lower voltage rating MLCC on this portion.
We are plan to use PVDD = 40V and GVDD = 12V.
So we guess BST cap is applied approx. 12V. There for we think we can change this cap to other cap which have lower voltage rating.
Then, I'd like to know about following points.
・Why schematics example used 100V MLCC?
・Is there recommended capacitance of BST cap as actual effective capacity.
Could you provide answer for above question?
Best regards,
Kazuki Kuramochi
