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.
