LB1875
Monolithic Digital IC
LB1875
Polygon Mirror Motor Predriver IC
Overview
The LB1875 is a predriver IC for polygon mirror motors.
By using a driver array or discrete
transistors (FETs) at the output, motor drive with high rotation precision is possible.
PAM drive or direct PWM drive can be selected for the output to realize high-efficiency control with minimum power loss.
