DRV8849: The design basis for the reference design

Tool/software:

Hi,

We are now consider to use the DRV8849 and we have below technology issue:

1. Please help explain why this capacitor is needed between the VM and VCP:

2. Please help to explain why this diodes are needed between the VCP and VCP1:

3. Please help to explain why the constant current source and pull-down resistor on the same circuit:

4. Please help to explain why the charge pump is connect to digital core but not directly connected to MOSFET gate:
