Description
The FAN8623 is an ASIC combination chip, designed for the
HDD application, It includes the following functions: spin-
dle motor drive, voice coil motor drive, retract and power
management.
To drive and control the spindle, the external ASIC provides
the appropriate control signals (Start up, commutation, speed
control) to the FAN8623. The spindle motor is monitored by
the FG output and the motor speed control is accomplished
via the PWMSP input. The ASIC controls the voice coil
motor current via PWMH and PWML inputs and the power
management circuit monitors the power supply voltages.
