Overview
The LB1821M 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 LB1821M
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 constraint protection
circuits, current limiter, and thermal shutdown
protection circuits.
