Description

The FAN8400D is a monolithic integrated circuit. it is one driver for laser beam printer (LBP) polygon mirror motor, which has single chip implementation of all circuits. For extremely high rotational precision, it employs the phase locked loop (PLL) speed control scheme.

Features

• 3-Phase BLDC motor driver IC with speed control

• Phase Locked Loop (PLL) speed control

• Built-in phase locked detector output

• Current linear drive scheme

• External clock for arbitrary motor speed

• Built-in FG amplifier and integrating amplifier

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

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

Typical application

• Polygon mirror motor drive IC for laser beam printer

• Polygon mirror motor drive IC for facsimile

• Polygon mirror motor drive IC for duplicator

• Polygon mirror motor drive IC for multi function printer

• General 3 phase BLDC motor drive IC
