PWM Speed Control for Permanent Excited DC Motors

The CCU2350 from Dialog Semiconductor provides pwm speed control for permanent excited dc motors of the type typically used in household appliances. The overall concept enables the construction of a power controller with mains voltage compensation where intermittent operation is also possible.

In addition, the circuit also enables mains-voltage compensated current control, which maintains the power supplied at a constant level after the preset threshold has been exceeded.

Applications are expected to include household consumer applications like food processors, domestic equipment, power tools, toys, and so on.
