Description
L7207 is a motor controller IC designed for both
desktop and dobile 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.
Linear voltage and switching regulators are
included, as well as a negative regulator and
power monitoring function.
L7207 embeds a serial interface with a maximum
speed of 40 MHz.
