DRV8312 Bulk Capacitance and Over Current Adjust

Customer is considering moving from an ST motor controller to DRV8312.  They have the evaluation board controlling their motor.

Questions:

1. Bulk capacitance.  The data sheet does not provide specific details on bulk capacitance.  Do we offer any rough guidelines?  Do you need 2 x 470 uFs or can the customer us 3 x 100 uFs?

2. OC_ADJ pin.  Is it possible to set the current limit with a voltage instead of a resistor to ground?  Customer would like to use a DAC or filtered PWM output with filter from the MCU instead of adding a digital potentiometer if I want to have software control of the current limit value.

Please advise.

Thanks,

Mark
