LB11921T
Overview
The LB11921T is a pre-driver IC designed for variable-speed 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 LB11921T includes a built-in VCO
circuit, applications can control the motor speed arbitrarily by varying the external clock frequency.
Functions
Direct PWM drive output
Speed discriminator + PLL speed control circuit
Speed lock detection output
Built-in VCO 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.
