DRV8833: which is the difference between DRV8833C and DRV8833?

Hello,

DRV8833C and DRV8833 are almost pin to pin compatible. But,

1. DRV8833C doesn't have charge pump circuit and doesn't require the VCP to VM ceramic capacitor.

2. Since DRV8833C doesn't have the charge pump circuit, the high side FET is PFET which has a higher Rds_on. DRV8833 high side FET is a NFET which has a lower Rds_on.

3. Since the Rds_on differences, DRV8833C supports 1A OCP current; DRV8833 supports 2A OCP current.

I would say DRV8833C is a low cost solution comparing DRV8833 if the output current is lower than 1A.
