Hi, sorry for the delay due to some equipment repairs. The phase current waveform is around 2 Hz at about 3 amp PP. Top speed is around 1.5 KHz. In slow speed lockup it will not respond to the speed...

Mike, There is not a DRV8332 EVM. Could you leverage the DRV8312 EVM which is similar in functionality? The difference, the DRV8312 does not have the current handling capability of the DRV8332. If this...

Hi Luis,We selected the DVR8332 precisely for its current handling capability. The DRV8312 does not meet our application requirement. TI should seriously consider facilitating testing and eventual...

Hi Rocky, Add resistor on all phases, because BEMF comparator is connected across 2 phases internally. Capacitor will cause inrush current since phase pin are switching between VCC and GND. I don't...

Update: Increasing the output resistance to ground to 150K still does not solve the problem. Is there a resistance in series or a voltage divider circuit inside the part?
