ACTUATOR DRIVER WITH CURRENT
FEEDBACK FOR CD – ROM / DVD
SA5694
DESCRIPTION
The SA5694 is a four-channel BTL driver IC for driving the motors
and actuators in products such as CD - ROM / DVD drivers. Two of
the channels use current feedback to minimize the current phase
shift caused by the influence of load inductance.
FEATURE
1.Wide dynamic range (4.0V (typ.) when VCC = 12V,
PVCC =5V, and RL = 8 ).
2. Level shift circuit on chip.
3. Thermal shutdown circuit on chip.
