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

• 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)
