When the auto…
Part Number: DRV8452 Tool/software: Dear team
I have some questions about the parameter "SS_KP", "SS_KI" "SS_KP_DIV_SEL", "SS_KI_DIV_SEL".
In the example on page 38, after calculating Kp, how can it be converted to the parameter of "SS_KP"?
As same…
Part Number: DRV8452 Tool/software: Dear Support Team,
DRV8452 issues an alert when it detects a STALL, but I don't think it automatically cuts off motor excitation, but I'd like to confirm just to be sure. Could you comment on the behavior after a…
Part Number: DRV8452 Tool/software: Hi,
I am using the DRV8452 in a system where power is controlled by an interlock mechanism:
Power is disconnected when the interlock is triggered.
Power is reconnected when the interlock is released.
Could…
