Part Number: DRV8840
Hi Team,
The demo board schematic and layout were made according to the TI official document. Customer set VREF with the DAC of the microcontroller. Risen=0.1R. Vref is 2A. OUT1 and OUT2 are connected to a 5 ohm resistor. But when he measured the current through the resistor, he found it was only 0.54A. I0-I5 has been fully raised.
He modified Vref to 1.5V, but the current is still 0.54A. He modified the I0-I5 current ratio, but still can't adjust normally. Two boards were experiencing the same issue. Customer would like to know how to resolve this issue？
Thanks.
Annie
