Overview
Ordering number : ENN6087A Monolithic Digital IC LB1975 DC Fan Motor Driver 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.
