LB1823M
Power Brushless Motor Predriver IC
for OA Applications
Overview
The LB1823M is a predriver IC developed for driving
power brushless motors in office automation applications.
A motor driver circuit with the desired output power
(current and voltage) can be constructed by attaching
either a driver array or discrete components at the output.
The LB1823M output supports direct PWM drive and thus
allows the implementation of low-loss drive circuits.
Additionally, the LB1823M includes several associated
circuits, such as a speed control circuit, and FG amplifier,
and an integrating amplifier, on chip.
Features
• Direct PWM drive output
• Crystal oscillator circuit
• Speed discriminator plus PLL speed control system
• Lock detector output
• Forward/reverse switching circuit
• Braking circuit (short braking technique)
• Start/stop switching circuit
• Over current limiter circuit (OCL)
• Thermal shutdown circuit (TSD)
• Built-in FG amplifier, integrating amplifier
• Shunt regulator output (7.0 V)
