LB11697V:Direct PWM Drive Brushless Motor Predriver
The LB11697V 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 LB11697V provides a full complement of protection circuits allowing it to easily implement high-reliability drive circuits. Note that the LB11697V is a modified version of the LB11696V in which the output logic has been optimized for 12 V system motors. This allows the number of external components to be reduced in application circuits.
