I've been searching the web for some information on Voice coil motor driver used in modern HDD.
I've found some info **broken link removed**. I've found datasheet for and old TI TLS2205 VOICE-COIL MOTOR DRIVER, SPINDLE-MOTOR DRIVER, AND VOLTAGE MONITOR chip. I'm trying to find datasheet for a 40GB Maxtor HDD VCM(voice coil motor) driver also from TI, but I can't find the datasheet. Perhaps I've misinterpret the numbering scheme/marking . It says (in the chip package):
TI DSP
040104200
D741864FPGF
CF-16A49CW
my question is: which one is the part number that I have to use to search for the datasheet? I've tried all of them with no result in TI's website. Or perhaps it can't be downloaded freely?
