Description
The FAN8621B, is a Bipolar monolithic stand-alone IC,
designed for 12V HDD applications.The internal power
stage consists of vertical PNP and NPN TRs for both SPM
and VCM, thus minimizing voltage drop, and increasing
drive capability up to 2A for SPM and 1.2A for VCM. This
device includes soft commutation drive to reduce audible
noise and intelligent retract function for decreased bouncing.
