LB1975-E

3相无刷直流电机驱动器

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.
