Direct PWM Drive Brushless Motor Predriver for OA Products
Overview
The LB11823M is a direct PWM drive predriver IC for use with three-phase power brushless motors. The LB11823M can implement a motor drive circuit with the desired output capacity (
voltage and current) by using appropriate external transistors. Due to its built-in FG amplifier and other features, this device is optimal for motor drive in OA products that use power brushless motors.
