HA13561F - Combo (Spindle & VCM) Driver

General Description

This COMBO Driver for HDD application consists of Sensorless Spindle Driver and BTL type VCM Driver.

Bipolar Process is applied and a “Soft Switching Circuit” for less commutation noise and a “Booster Circuit’ for smaller Saturation Voltage of Output Transistor are also implemented.

Key Features

  • Soft Switching Driver Small Surface Mount Package: FP-80E (QFP80 Pin) Low thermal resistance: 35°C/W with 6 layer multi glass-epoxy board.
  • Low output saturation voltage  Spindle 0.8 V Typ (@1.0 A)  VCM 0.8 V Typ (@0.8 A) Functions.
  • 1.8 A Max/3-phase motor driver 1.2 A Max BTL VCM Driver Auto retract Soft Switching Matrix Start up circuit Booster Speed Discriminator Internal Pr.
