Direct PWM Drive Brushless Motor Predriver for On-Demand Water Heater and Air Conditioner Motors
Overview
The LB11824M is a direct PWM drive predriver IC for use with three-phase power brushless motors. The LB11824M can implement a motor drive circuit with the desired output capacity (voltage and current) by using appropriate external
transistors. This device is optimal for motor drive in larger home appliances such as air conditioners and on-demand hot water heaters.
