Description
The KA2811C is a monolithic one-chip IC which includes
SPM (Spindle motor) driver, VCM (Voice coil motor) driver
and peripheral driver, designed for driving HDD motor. For
high starting torque and high speed, SPM circuit employes
WSS (Waltz step start) method for starting the motor and can
drive up to 2A. VCM circuit is designed to drive up to 1.5A
to meet the trends of HDD'S high speed. (Requires external
transistors).
48-QFPH-1414
Typical Applications
