摘要： A push-pull driver is provided with a differential amplifier that amplifies a difference between an input voltage and an output voltage to drive a bias node coupled to a diode-connected bias transistor. The push-pull driver is configured to control the drain-to-source voltage for a source-follower output transistor having its gate tied to a gate for the diode-connected bias transistor to be proportional to the drain-to-source voltage for the diode-connected bias transistor. This proportionality prevents excessive static current variation that would otherwise be present in the source-follower output transistor.

摘要： A sampling circuit may include a sampling capacitance, an electronic sampling switch, and a switch controller. The electronic sampling switch may have a control input that controls whether the electronic sampling switch is in a sample state or a hold state. The electronic sampling switch may connect the sampling capacitance to an input signal while in the sample state and disconnect the sampling capacitance from the input signal while in the hold state. The switch controller may control the control input to the electronic sampling switch so as to cause the electronic sampling switch to be in the sample state during one period and the hold state during another period. While in the sample state, the switch controller may cause the impedance of the electronic sampling switch that is seen by the input signal to be substantially independent of the voltage of the input signal. The switch controller may include a pre-charge circuit that pre-charges the control input to the electronic sampling switch prior to each commencement of the sample state to approximately the average of the voltage of the input signal and the voltage on the sampling capacitance immediately prior to each commencement of the sample state. The amount of the pre-charging may be substantially independent of the voltage of the input signal.

摘要： Le relais statique (1, 10, 18, 19) de commande d'un démarreur électrique (2) de véhicule automobile selon l'invention est du type de ceux comprenant en série dans un circuit d'alimentation électrique du démarreur, formant charge inductive, un premier commutateur à semi-conducteur de puissance (4) et au moins un second commutateur à semi-conducteur de puissance (11). Le premier commutateur et le second commutateur effectuent une opération de commutation. Le premier commutateur effectue en outre une opération de démagnétisation de la charge inductive et le second commutateur a en outre une fonction de sécurité. Conformément à l'invention, le second commutateur effectue en outre ladite opération de démagnétisation. Selon une autre caractéristique de l'invention, le premier commutateur effectue l'opération de démagnétisation au moyen d'un premier circuit de clampage actif (8) et le second commutateur effectue l'opération de démagnétisation au moyen d'un second circuit de clam page actif (31).

摘要： With a relay control device (1) according to an embodiment, a regenerative current from a relay coil (5b) which is disposed in a relay (5) flows through a coil energy absorption circuit (7), which is connected to the low side of the relay coil (5b), toward the ground. A current detection resistor (Rsens), which is a shunt resistor, is connected further toward the ground side of the coil energy absorption circuit (7) than a coil surge absorption resistor (Rsup), and the potential (Vsens) of the current detection resistor (Rsens) is compared to a reference potential (Vref), with a current detection circuit (13). Furthermore, on the basis of the result of the comparison with the current detection circuit (13), an off-duty period of the PWM control is terminated before the current (Icoil) which flows through the relay coil (5b) becomes less than or equal to a minimum drive current (Iset).
