Monolithic Digital IC  
For Office Automation Equipment  
LB1929  
3-phase Brushless Motor Driver  
Overview  
The LB1929 is a 3-phase brushless motor driver well suited for drum and paper feed motors in laser printers, plain-paper  
copiers and other office automation equipment. Direct PWM drive allows control with low power losses. Peripheral circuitry  
including speed control circuit and FG amplifier is integrated, thus allows drive circuit to be constructed with a single chip.  
Features  
3-phase bipolar drive (30V, 3.5A)  
Direct PWM drive technique  
Built-in diode for absorbing output lower-side kickback  
Speed discriminator and PLL speed control  
Speed lock detection output  
Built-in forward/reverse switching circuit  
Built-in protection circuitry includes current limiter, overheat protection, motor restraint protection, etc.
