LB11870
Overview
The LB11870 is a three-phase brushless motor driver developed for driving the motors used with the polygonal
mirror in laser printers and plain paper copiers. It can implement, with a single IC chip, all the circuits required
for polygonal mirror drive, including speed control and driver functions. The LB11870 can implement motor drive
with minimal power loss due to its use of direct PWM drive.
Functions
Three-phase bipolar drive
Direct PWM drive
Includes six high and low side diodes on chip.
Output current control circuit
PLL speed control circuit
Phase lock detection output (with masking function)
Includes current limiter, thermal protection, rotor constraint protection, and low-voltage protection circuits on chip.
Deceleration type switching circuit (free running or reverse torque)
PWM oscillator
Power saving circuit
Ordering number : EN7256A
Monolithic Digital IC
For Polygonal Mirror Motors
Three-Phase Brushless Motor Driver
