Overview
The LB1975 is a three-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 45 V, output current 2.5 A
• Direct PWM drive output
• 3 built-in output top-side diodes
• Built-in current limiter
• Built-in FG output circuit
