Monolithic Digital IC
Power Brushless Motor Pre-Driver IC for OA Equipment
Overview
The LB1821M is a pre-driver IC that supports direct PWM drive and is appropriate for the power brushless motors used in office automation equipment. A motor drive circuit with the desired output capability (voltage and current characteristics) can be constructed by attaching a driver array at the IC output. The LB1821M includes on chip a speed control circuit that allows the motor speed to be varied using an external clock.
