KA2811C General 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).

KA2811C Maximum Ratings

Parameter	Symbol	Value	Unit
Maximum supply voltage	V_CC1MAX, V_CC1MAX	15.0	V
Maximum logic part supply voltage 2	V_CC3MAX (V_DD)	7.0	V
Power dissipation	P_D	3.0	A
Maximum output drive current	I_OMAX	2.0	W
Logic control input voltage	V_IN	-3.0 ~ V_CC3	V
Operating temperature range	T_OPR	0 ~ 70	°C
Soldering temperature (5 seconds, 1/4 inch from pin)	T_SOLD	300	°C
Storage temperature range	T_STG	-55 ~ 150	°C

Notes:
1. Absolute maximum ratings are values beyond which the device may be damaged permanently. Normal operation is not guaranteed at or above those extremes.
2. All voltages are measured with respect to the GND voltage level unless otherwise specified.
3. When mounted on 50mm × 50mm × 1mm PCB (Phenolic resin material).
4. Do not exceed Pd and SOA(Safe Operation Area).
