摘要

A control circuit, in particular for a direct current motor control in positioning systems, has a differential circuit (1), control logic (2) and a full bridge (3) connected between a supply voltage VS and a reference potential GND. The differential circuit (1) has a first hysteresis comparator (HC1) and a second hysteresis comparator (HC2). Both comparator inputs (HC1-, HC1+, HC2-, HC2+) of both hysteresis comparators (HC1, HC2) are connected each to one of the two input terminals (IN1, IN2) of the control circuit and crosswise to a comparator input of the other comparator (HC1, HC2). The inverting input of each comparator (HC1, HC2) is connected to the non-inverting input of the other comparator.
