LB1975 is a 3-phase brushless motor driver IC suited for use in direct PWM driving DC fan motors for air conditioners, water heaters and other similar equipment. Because a shunt regulator circuit is built in, single power supply operation sharing the same power supply for the motor is supported.

• Withstand voltage 46 V, output current 2.5 A
• Direct PWM drive output
• 3 integrated output top-side diodes
• Integrated current limiter
• Integrated FG output circuit
