www.fairchildsemi.com

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)

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.

28-SSOPH-375SG2

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
