Hi! I have 4 TAS5630 synchronized together. They works in BTL Mode.
PVDD supply: 1000 VA toroidal transformer, 45VDC.
GVDD and VDD: a smaller transformer, 12VDC,
I have a soft start circuit for toroidal transformer. So the PVDD and VDD supply can't start at the same time. PVDD delays 3 sec.
Is it a problem? What happend if the device gets the VDD/GVDD (12V) suply without PVDD. Can I start PVDD any time?
VDD/GVDD running....Is SD pin active until the device gets PVDD?
What happens inversly? PVDD first, VDD second ? And SD pin?
Thanks.
