Monolithic Digital IC

LB1813M

FDD Spindle Motor Driver

Overview

The LB1813M is 3-phase DD motor driver IC and is an
ideal FDD spindle motor driver for 3.5 inch applications.

Features

• Three phase total wave linear driver.

• Eliminates need for output electrolytic capacitor
(however, depending on the motor, this may not apply)

• On-chip digital speed control : fosc=(1024×fFG)/D
When SL1=high D=5/8
SL1=low D=6/8

• Start/Stop circuit.

• Rotation speed switching.

• Current limiter circuit.

• On-chip index comparator (single hysteresis)

• On-chip index delay circuit.

• AGC circuit.

• Thermal protection circuit.
