LB11824M
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.
Features
Three-phase bipolar drive
Direct PWM drive
Built-in forward/reverse switching circuit
Full complement of built-in protection circuits, including current limiter, undervoltage protection circuit, motor lockup
protection circuit, and thermal protection circuit.
Can be controlled by either a command voltage or the duty of an input PWM signal.
Provides three types of Hall-effect element signal pulse outputs.
