LB1814M
Overview
LB1814M is a driver IC that was developed to drive 3.5-inch magneto-optical disk spindle motors. It integrates all the
necessary functions, including the speed control circuit, drive circuit and other functions on a single chip. Using a
current linear drive technique for minimal motor drive noise and PLL speed control circuit with excellent jitter
characteristics, this IC offers selectivity in the methods for FG input and reference clock input, enabling it to support a
wide range of applications. With a view to interfacing with equipment controllers (e.g., of microcontrollers), it comes
with a variety of outputs that can be used to monitor the motor operation.
