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.
