HA13536F
Three-Phase Brushless DC Motor Driver IC
ADE-207-111B (Z)
3rd Edition
July 1996
Description
The HA13536F is a 3-phase brushless DC motor driver IC with digital speed control. It is being developed
for direct drive of the spindle motor of 5 V floppy disk drives with a height of 3/4" or less. It has the follow-
ing functions and features.
Functions
• 1.0 A per phase, 3-phase drive circuit (current driver)
• Digital speed control circuit
• FG Amp
• Index circuit
• Current limiter circuit
• Over-temperature shutdown circuit (OTSD)
Features
• Low saturation voltage, typically 1.15 V (at 0.7 A)
• Soft switching drive circuit
• No need for an output snubber circuit
