Three-Phase Brushless Sensorless Motor Driver
LB1950V
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
