Overview

The LB1976 is a 3-phase brushless motor driver IC suited for use in direct PWM driving of DC fan motors for air conditioners, water heaters, and other similar equipment. Since a shunt regulator circuit is built in, single power supply operation sharing the same power supply for the motor is supported.

Features

• Withstand voltage 60V, output current 2.5A

• Direct PWM drive output

• 3 built-in output top-side diodes

• Built-in current limiter

• Built-in FG output circuit
