Driver for 3.5inch HDD motor

New Reduce external components and improve reliability For 3.5inch HDD Motor Comb IC/AN8428GAK ■ Overview AN8428GAK is motor comb IC for 3.5inch HDD. By new retract circuit ,reduce external components and shorten the brake time of the disk to improve reliability of HDD . Spindle motor sensor less linear drive. VCM linear drive , PWM-DAC control . Built-in Retract , 12 V/5 V/3.3 V power monitor, 3.3 V-Regulator. 80-pin TQFP package with exposed heat think . Unit : mm ■ Features ●By new retract circuit ,reduce external components and shorten the brake time 1/2 of the disk to improve reliability of HDD . ●Built-in shock sensor amplifier for mechanical shock protection and 3.3 V regulator for logic semiconductor . ●10 dB acoustic noise reduction by trapezoidal current on spindle motor drive . ●80- pin TQFP package with the smallest thermal resistance in the industry . Meet to increase speed of HDD higher 30 % than previous. HQFP080-P-1414 ■ Principle functions (1)Spindle motor sensor less linear drive :2.7 A peak current drivers , Ron=1.1 Ω (2)VCM linear drive : 1.8 A peak current , Ron=1.5 Ω (3)Retract function exists (4)Built in 12 V/5 V/3.3 V power monitor (5)Built in shock sensor amplifier (6)Built in 3.3 V regulator ■ Applications 3.5 inch HDD The products and specification are subject to change without any notice.
