LB1923M
Overview
The LB1923M is a pre-driver IC that supports direct PWM drive and is appropriate for the power brushless motors used
in office automation equipment. A motor drive circuit with the desired output capability (voltage and current
characteristics) can be constructed by attaching a driver array at the IC output. The LB1923M includes on chip a speed
control circuit that allows the motor speed to be varied using an external clock.
Features
Direct PWM drive output
Speed discriminator + PLL speed control circuit
FG and integrating amplifiers
Forward/reverse switching circuit
Braking circuit (short braking)
Speed lock detection output
Full complement of on-chip protection circuits, including lock protection, current limiter, and thermal shutdown
protection circuits.
