Monolithic Digital IC
LB1882V
Three-Phase Brushless Motor Driver
Overview
The LB1882V is a three-phase brushless motor driver IC
that is particularly well-suited for driving spindle motors
in portable AV equipment such as DAT, CD and MD
products.
Features
• Current linear drive: allows external capacitances to be
minimized.
• Motor voltage control: reduces power dissipation.
• Support for motor drive at power supply voltages as low
as 1.8 V
• Built-in torque ripple correction circuit
• Built-in saturation prevention circuit
• Built-in AGC circuit
• Built-in thermal shutdown circuit
• Built-in current limiter
• Built-in FG amplifier
