Overview
The LB11875 is a pre-driver IC developed for driving
motors such as the polygonal mirror motor used in laser
printers. A motor drive circuit with high rotational
precision can be implemented by using either a driver
array or discrete transistors (FETs) at the LB11875’s
outputs. The LB11875 achieves low power even at large
currents by adopting direct PWM drive.
Features and Functions
Three-phase bipolar drive (direct PWM drive)
PLL speed control circuit
Speed control by an external clock signal
Supports Hall sensor FG operation
Clock divisor switching function
Phase lock state detection output (with mask function)
Inculudes current limiter, thermal protection, rotor
constraint protection, and low-voltage protection
circuits.
