LB11824M
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.
Functions and 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.

When S/S and PWMIN pins are not used, set the input to the L level voltage.
For HP output, pulsed output of Hall input IN1 (1-Hall output), 1/2 division output of 1 Hall, or synthetic output of three
phases of Hall input (three-Hall synthetic output) may be selected.
