LB11873
Overview
The LB11873 is a 3-phase brushless motor driver developed for driving the polygonal mirror motor used in plain-paper
copiers and similar products. This IC can implement the circuits required for polygonal mirror motor drive (speed control
and driver circuits) in a single chip.
The LB11873 implements low-noise/low-vibration PWM drive by changing the current at phase switching gradually to
reduce motor noise.
Functions
Three-phase bipolar drive (quiet direct PWM)
PLL speed control circuit
Hall sensor FG support
Dedicated external clock
Brake mode switching circuit (free running and reverse braking)
Phase lock detection output (with masking function)
Built-in current limiter, constraint protection, undervoltage protection, thermal protection, and CLK line disconnection
protection circuits
Input pins support 3V system microcontrollers
