Reduce external components and improve reliability

For 3.5inch HDD Motor Comb IC／AN8428GAK

■ Overview

Unit : mm

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 .

■ 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 .

HQFP080-P-1414

●80- pin TQFP package with the smallest thermal resistance in the

industry .

Meet to increase speed of HDD higher 30 % than previous.

■ 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
