FAN8400D (FAN8400BD3)
3-Phase BLDC Motor Driver with PLL
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
