LB1923M
Power Brushless Motor Pre-Driver IC
for OA Equipment
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.
