System motor driver for CD/DVD Player
4ch System Motor Driver
for Car Audio
BD8266EFV-M
●General
Description
BD8266EFV-M is BTL driver of 5 inputs and 4 outputs
for Car CDs developed for SPINDLE motor (CH1),
SLED/LOADING motor (CH2) and coil drive for
actuator(CH3:TRAKING CH4:FOCUS).
It can drive motor and coil of the CD/DVD drive.
●Features
Drive at PowVCC=5V and 8V with wide Maximum
Output Amplitude .
Switches SLED/LOADING input by CNT terminal.
Incorporates mute function by CNT terminal and
MUTE terminal.
Preventing the overcurrent to the load by the FOCUS
Over Current Protection (OCP) function.
Built-in TSD, UVLO.
PowVCC1 and PowVCC2 are independent,
and an efficient drive is possible.
PowVCC1 : for SPINDLE&SLED/LOADING.
PowVCC2 : for TRAKING & FOCUS.
AEC-Q100 Qualified
