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
