Hi Aoyama-san, You are correct. There is an analog circuit to limit the current.
View ArticleRE: DRV8701: use in 1/2 bridge mode for 2 motors?
Hello, yes, both motors should run at the same time. Both are 30V/150W. They should be controlled each with PWM. Internal OPAs are prefered. At the moment the use DRV8323 but then 1 HB is not used....
