com Silan Semiconductors ACTUATOR DRIVER WITH CURRENT FEEDBACK FOR CD – ROM / DVD 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.
SA5694 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.
