Description
L7208 is available in an ultra-thin package and is
optimized for 1.8 inch and sub-1.8 inch consumer
equipment drives.
The spindle motor driver subsystem integrates all
power FETs driven by ST's Smooth Drive®
commutation technology.
The voice coil driver block includes the power
FETs, emergency retract function as well as ramp
load and unload capability.
Positive and negative regulators are integrated
together with provision for shock sensing and
free-fall detection.
Extremely low power consumption, in all modes of
operation, is achieved by an optimized chip
partitioning enabling extended battery life in
consumer applications.
L7208 embeds a serial interface with a maximum
speed of 50 MHz.
