Overview
The LB1950V is a 3-phase brushless sensorless motor driver IC that is particularly well-suited to driving camcorder drum motors.

FEATUREs
• Drives 3-phase full-wave brushless sensorless motors
• Soft switching drive
• Speed control using motor power-supply voltage control for reduced power
• Allows operation from a 3-V power supply.
• The residual output voltage can be set to one of four values.
• Supports bidirectional rotation.
• Standby function (only the FG and PG amplifiers operate)
• Brake circuit
• Thermal shutdown circuit
• FG and PG amplifiers
