TAS5342LA: VDD and PVDD

Akio Ito
Genius 3595 points
Part Number: TAS5342LA

Hi,

A customer's product will supply 32V to PVDD even if VDD power is not supplied.
In this state they call standby mode, the MPU power is supplied, but almost circuits including PWM output stop operating.
Is there any problem?

Best regards,
