AN8428GAK Datasheet Driver For 3.5inch Hdd Motor

Manufacturer: Panasonic

Overview: New Reduce external ponents and improve reliability For 3.5inch HDD Motor b IC／AN8428GAK ■ Overview AN8428GAK is motor b IC for 3.5inch HDD. By new retract circuit ,reduce external ponents 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 .

Key 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.
