Description

The E910.06 Dual Ripple Counter is used in conjunction with a microcontroller to operate two DC motors. It accepts instructions from the microcontroller and generates the control signals for two Power MOS full bridge circuits (one for each motor). Besides it also detects the commutator ripple of the motors (no additional sensor needed), and provides this, along with full bridge diagnostic information, back to the controller.
