LB1976 Datasheet (ON Semiconductor) - Three-Phase Brushless Motor Driver

LB1976, Three-Phase Brushless Motor Driver

LB1976 1.

Direct PWM Drive The LB1976 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 pr
