Hello guys,
One of my customers is about to start designing of their new products using DRV8702-Q1. They had the following question when they were checking DRV8702-Q1 datasheet.
Could you please answer the following question?
Q. They calculated I(CHOP) with Equation1 on page 24 in DRV8702 datasheet. Then they used the parameters described at same section as the below.
Vvref=3.3V, VIO=50mV, R(sense)= 50mohm, Av=19.8V/V.
But they didn't get 3.28A as the answer described at same sectin.
Their question is whether the Equation1 in DRV8702-Q1 datasheet (SLVSDR9D) is correct or not.
Your reply would be much appreciated.
Best regards,
Kazuya Nakai.
