Monolithic Digital IC  
For Polygon Mirror Motors  
LB1876  
3-phase Brushless Motor Driver  
Overview  
The LB1876 is a driver for polygon mirror motors such as used in laser printers and similar equipment.  
It incorporates all necessary circuitry (speed control + driver) on a single chip. Direct PWM drive enables drive with low  
power loss.  
Features  
3-phase bipolar drive  
Direct PWM drive technique  
Built-in lower side output diode  
Output current limiter  
Reference clock input circuit (FG frequency equivalent)  
PLL speed control circuit  
Phase lock detector output (with masking function)  
Built-in protection circuitry includes current limiter, restraint protection, overheat protection, low-voltage protection, etc.  
Brake method switching circuit (free-run or reverse torque)  
5V regulator output  
Power save function
