Description

The FAN8403D3 is a monolithic integrated circuit. It is suitable for polygon mirror motor of laser beam printer (LBP).

Features

• 3-Phase BLDC motor drive IC with speed control

• Phase Locked Loop (PLL) speed control

• Built-in phase locked detector output

• External clock for control of motor speed

• Built-in FG amplifier and FG schmidt comparator

• Built-in integrating amplifier with phase error

• Auto Gain Control (AGC) circuit for compensation hall amplifier

• Built-in protection circuits (over-current limit, undervoltage limit, thermal shut down)

Typical application

• Polygon mirror motor for laser beam printer

• Polygon mirror motor for facsimile

• Polygon mirror motor for duplicator
