Overview
Ordering number : ENN7498 Monolithic Digital IC LB11923V Three-Phase Brushless Motor Driver Overview The LB11923V is a pre-driver IC designed for variablespeed control of 3-phase brushless motors.
It can be used www.
DataSheet4U.
com 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.
