[ DRV8662 ] Back EMF from Piezo

Hi,

Can you help me to understand that how DRV8662 tolerate the back emf from its piezo actuator? I have seen some of piezo driver has back emf detection circuit inside of driver, however, from block drawing of DRV8662, it cannot be seen.


It's appreciated if you can share some of ideas about DRV8662 and its back emf effect.
Thanks,
Ken
