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). |
