LB1975 DC Fan Motor Driver

Direct PWM Drive This IC (LB1975) employs the direct PWM drive principle. Motor rotation speed is controlled by varying the output duty cycle according to an analog voltage input (VCTL). This eliminates the need to alter the motor power supply voltage. Compared to previous ICs using the PAM principl.
