This is gull wing 64pin QFP IC w/ three sections within, unique ASIC
for both of spindle motor and voice coil drivers all in one IC.
Been looking for a one to pluck from crashed HD to fix mine that IC
had burned up.
Search on 'net didn't find cross reference for it but I know that few
makers like Quantum did use at least two brands of this same for
TDA5147K and AN8425NFEG-A. But both are for PLCC. This one I want
is 64pin QFP.
I have quite bunch of HDs w/ similar looking ICs but need to know of
suitable substitute IC.
Cheers,
Wizard
PS: I have both data sheets for TDA5147(CH and K).
