Monolithic Digital IC
LB11695M
Direct PWM Drive Brushless Motor Predriver
IC for Hot Water Heaters and Air Conditioners
Overview
The LB11695M is a direct PWM drive predriver IC designed for three-phase power brushless motors. A motor driver
circuit with the desired output power (voltage and current) can be implemented by adding discrete transistors in the output
circuits. This device is optimal for driving all types of large-scale motors such as those used in air conditioners and
on-demand water heaters.
Functions and features
• Three-phase bipolar drive
• Direct PWM drive
• Built-in forward/reverse switching circuit
• Many protection circuits including current limiter circuit, undervoltage protection circuit, constraint protection circuit,
and thermal protection circuit
• Supports control by command voltage or PWM duty input.
• Four types of Hall signal pulse outputs
