Description
L7220 is a motor controller IC designed for both
enterprise and multi-platter desktop hard disk
drive applications.
The spindle motor driver subsystem integrates all
power FETs driven by ST’s SmoothDrive
commutation technology.
The voice coil driver block includes the power
FETs, as well as ramp load and unload capability.
Hysteretic switching regulator controllers are
included.
L7220 embeds a serial interface with a maximum
speed of 60MHz.
