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
