LB1976 Product details

Description

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 principle (such as the LB1690), this allows simplification of the power supply circuitry.The VCTL input can be directly supplied by a microcontroller, motor speed can, therefore, be controlled directly
