LB1823
Power Brushless Motor Predriver IC
for OA Applications
Overview
The LB1823 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 LB1823 output supports direct PWM drive and thus
allows the implementation of low-loss drive circuits.
Additionally, the LB1823 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
