HA13565F
Three-Phase Brushless DC Motor Driver IC
ADE-207-226A (Z)
2nd. Edition
April 1997
Description
HA13565F is a 3-phase brushless DC motor driver IC with digital speed control. It is developed for direct
drive of the spindle motor of 5V floppy disk drives. It has the following functions and features.
Functions
• 3 sensor 1.0A/phase, 3-phase drive circuit
• Digital speed control circuit
• Sensorless index circuit
• Current limiter circuit
• Over-temperature shutdown circuit (OTSD)
• Circuit for switching between 300 and 360rpm speeds
Features
• Low saturation voltage 0.5V Typ (at 0.7A)
• Soft switching drive circuit
• Small surface mount package
