tony li61324

Part Number: DRV10987

Dear Tier

DRV10987 datesheet 8.4.1.1 describe Motor Phase Resistance 。Don't understand Ry Rph_ct=Ry, Rph_ct It's always 1?

Hi Tony,

You are correct, this section is incorrect. the formula should be RPH_PH *1/3 = Ry . We are going to fix this error in the next datasheet.
