CCU2350
CCU2350 is PWM Speed Controller manufactured by Renesas.
PWM Speed Control for Permanent Excited DC Motors
General Description
The monolithic integrated bipolar circuit CCU2350 is a MOSFET or IGBT-control circuit which works on the principle of pulse width modulation (PMW). The overall concept enables the construction of a power controller with mains voltage pensation where intermittent operation is also possible. In addition, the circuit also enables mains-voltage pensated current control, which maintains the power supplied at a constant level after the preset threshold has been exceeded.
