Monolithic Digital IC
For Fan Motor
3-phase Brushless Motor Driver
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
