Monolithic Digital IC
LB1822
3-Phase Brushless Motor Predriver
with Digital Speed Control
Overview
The LB1822 is a monolithic predriver IC for controlling
three-phase brushless motors and has an on-chip digital
speed control circuit. The LB1822 is ideally suited for
driving the motor of laser beam printers, facsimiles, plain
paper copiers, and so on.
Features
• 30V withstand voltage and 30mA output current.
• Current limiter.
• Low-voltage protection circuit.
• Thermal shutdown circuit.
• Hall amp with hysteresis characteristic.
• Start/Stop terminals.
• Crystal osillator and divider.
• Digital speed control circuit.
• Lock detector.
