LB11993W
Monolithic Digital IC
For Digital Video Camera
Three-phase Brushless 3-in-1 Motor Driver
www.DataSheetO4Uv.ceomrview
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.
Functions
• Capstan unit
Voltage linear drive
Built-in torque ripple compensation circuit
FG amplifier
• Drum unit
Current drive
Sensorless drive
FG amplifier
PG amplifier
• Loading unit
2-channel reel amplifiers
• Common unit
Thermal shutdown circuit
2-channel OP amplifiers
