Abstract

An integrated circuit voltage stabiliser regulates the speed of a DC motor by two parallel current circuits, one being a linear function of the other. Current limiting thermal protection is provided. The output terminal (3) is connected to a motor in series with a voltage source and to a comparator (11). A second terminal (2) is connected to the junction of two resistors across the motor terminals. This terminal is connected to the comparator through a reference stage (10) with a constant current source (12). The comparator provides a voltage difference output to control two output transistors (13, 14). A temperature sensitive transistor (15) cuts off these transistors when the temperature reaches a preset level.
