LB11696V: Direct PWM Drive Brushless Motor Predriver
LB11696V is a direct PWM drive brushless motor predriver IC designed for 3-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.
Features- Direct PWM drive, controlled either by control voltage or PWM variable duty pulse input
- Built-in forward/reverse switching circuit
