Monolithic Digital IC
LB11923V
Three-Phase Brushless Motor Driver
Overview
The LB11923V is a pre-driver IC designed for variable-
www.DataSheet4sUp.eceodmcontrol 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 built-
in VCO circuit, applications can control the motor speed
arbitrarily by varying the external clock frequency.
Features
• Direct PWM drive output
• Speed discriminator + PLL speed control circuit
• Speed lock detection output
• Built-in crystal oscillator circuit
• Forward/reverse switching circuit
• Braking circuit (short braking)
• Full complement of on-chip protection circuits,
including lock protection, current limiter, and
thermal shutdown protection circuits.
