DRV8833: DRV8833 auto version

Tool/software:

HI Team, 

do we have plan for DRV8833 auto version?

my customer like DRV8833 hardware 4 wire PWM control. And they are asking do we have similar products in auto grade?

the application is lens focus adjustment. I promoted DRV8434-Q1. Customer think 1 PWM interface is too slow to adjust. Any suggestions? Thanks.
