LB11923V General Description
The LB11923V is a pre-driver IC designed for variablespeed control of 3-phase brushless motors. It can be used to implement a motor drive circuit with the desired output capacity (voltage, current) by using discrete transistors for the output stage. It implements direct PWM drive for minimal power loss. Since the LB11923V includes a builtin VCO circuit, applications can control the motor speed arbitrarily by varying the external clock frequency.
