... For brush motors H-bridge drivers (18V max.) BD6220, BD6221, BD6222, BD6225, BD6226, BD6227 Overview These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a wide range of power supply voltages (from 3V to 36V), supporting output currents 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs ...

... BD6220, BD6221, BD6222, BD6225, BD6226, BD6227 e) f) PWM control mode The rotational speed of the motor can be controlled by the switching duty when the PWM signal is input to the FIN pin or the RIN pin. In this mode, the high side output is fixed and the low side output does the switching, corresponding to the input signal. The switching operates by the output state toggling between " ...
