Description

The FAN8620B is an ASIC combination chip, designed for the HDD application, it includes the following functions: spindle 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 FAN8620B. The spindle motor condition 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 always monitors the power  supply voltages.
