Abstract: The invention relates to a loop-type voltage regulating device (10), particularly for regulating a voltage of an automotive electric system, being of a type which includes at least one thermal engine (15), a voltage regulator (13) and an alternator (11) operative to deliver a system regulated-voltage signal (A+) to and receive a regulation signal (DF) from the voltage regulator (13). Advantageously, according to the invention, the voltage regulating device further includes a control unit (14) within the regulating loop, which unit is connected between the thermal engine (15) and the voltage regulator (13) and is adapted to supply the latter with a signal related to the engine operation.

Abstract: A voltage-regulator circuit with a low voltage drop using a DMOS power transistor (PT) driven by a charge pump (CP) comprises two feedback loops: a first feedback loop having high gain and accuracy but low response speed, and a second feedback loop having a wide passband and fast response speed but low gain.

Abstract: In order to achieve a high input dynamic range as well as high CMRR and PSRR values and input impedance with the use of a single supply voltage (Vcc), the amplifier includes an input stage with two transistors (Q1, Q2) which are biased by a constant current (IP3, IP4), preferably of less than 1 microampere, and the collectors of the transistors (Q1, Q2) are kept at fixed reference voltages (VR1, VR2). The input signal (VIN) applied between the emitters (IN(-), IN(+)) of the transistors (Q1, Q2) is transferred to the terminals of a first resistor (R1) which is supplied with current (IR1) from a circuit (M7, A5, R3; M10, Q6, R4; M9, Q7, R5) which mirrors the current (IR1) into a second resistor (R6), from the terminals of which the output signal (VOUT) is taken. The preferred application is for forming interfaces for lambda probes fitted to catalytic converters for motor vehicles.

Abstract: The circuit includes two output terminals (OUT1, OUT2) for connection to the terminals of a load (L), first and second pairs of electronic power switches (Q1, Q4; Q2, Q3) which are connected between the output terminals (OUT1, OUT2) and the two poles of a direct-current voltage supply (Vs) so as to form an H-shaped structure with the load (L), and a driver circuit (C1, C2) for selectively making the electronic power switches of the first pair (Q1, Q4) of the second pair (Q2, Q3) order to cause a current to flow through the load (L) in one direction or the other respectively, and for preventing the electronic switches (Q1, Q3; Q2, Q4) which are connected between the same output terminal (OUT1; OUT2) and the two poles of the voltage supply (Vs) from conducting simultaneously.
