Part Number:DRV8303
Hi,
My customer has a question regarding the DRV8303 and its internal 6V analog supply on AVDD pin: Can I apply an external 5V to this pin through a Schottky diode so that when PVDD is missing, the two amplifiers can still work?
The gains could switch back to the default value or stay at whatever was programmed in prior to the PVDD loss. When the PVDD is restored, the internal 6V will come back up and turn off the diode. The maximum voltage at the input of these two amps will be around 1.5V at all times.
Thanks,
Chuchen
