Overview

The LB11696V 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. Furthermore, the

LB11696V provides a full complement of protection circuits allowing

it to easily implement high-reliability drive 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.
