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 and Features
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
