Overview
The LB11993W is a 3-phase brushless motor driver for digital video camera. It integrates, on a single chip, three motor driver functions (for capstan, drum, and loading motors) for driving a tape. This IC also includes 4-channel operation amplifiers (2 channels for reel and 2 channels for general purpose), which significantly reduces the number of peripheral components required.
