LB11696VGEVB: Direct PWM Drive Pre-Driver IC Evaluation Board

Evaluation/Development Tool Description

The LB11696V is a direct PWM drive pre-driver 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.
