LB1875

Ordering number : EN6002 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.
