    Abstract: The interface circuit (IC) has a single input terminal (i) for to receiving an analogue or digital (PWM) control signal (Vin) indicative of the required speed of rotation of the motor (M). The type of input signal (Vin) is recognised by means of comparator circuits (C1, C2). The input signal (Vin) is processed differently according to its nature in order, in any case, to output an analogue signal (Vo) acceptable by the regulation and control circuit (Z) which pilots the motor (M).

    Abstract: The circuit comprises a measurement resistor (Rs) in series with the heater (16, 28), a detector circuit (20) for providing a signal (VOP) indicative of the current flowing in the resistor (Rs), switching devices (PW1, PW2; PW3, PW4) for controlling the connection of the heater (16, 28) to a direct-current voltage source (Vbat) and the connection of the measurement resistor (Rs) in the supply circuit comprising the source (Vbat) and the heater (16, 28), and a control unit (18, 32) arranged to drive the switching devices (PW1, PW2; PW3, PW4) in a manner such that, each time the heater (16, 28) is activated, the measurement resistor (Rs) is kept disconnected from the supply circuit of the heater (16, 28) for a predetermined period of time and the measurement resistor (Rs) is then connected in the supply circuit of the heater (16, 28).
