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.
