Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

*An external diode from the input to the VIN pin is required if bootstrapping VDRV and VIN off of the output voltage.
