    • In an anti-ESD protective structure, especially designed for pins destined to reach below ground and/or above supply voltages, includes a pair of Zener diodes or lateral NPN structures with a resistive connection between base and emitter, connected in opposition among each other between the pin to be protected and a grounded substrate of the integrated circuit. An amplifying effect on the leakage current which is drawn/injected through the pin by the protective structure caused by the triggering of an intrinsic parasitic transistor is effectively eliminated by connecting a biasing element, such as a forward biased junction, between the node of interconnection between the two Zener orlateral NPN structures and a node of the integrated circuit biased with a voltage sufficiently high as to ensure, under any condition, a reverse biasing of the base-emitter junction of the parasitic transistor.

    • Saturation of a bipolar power transistor is controlled by sensing the current which is eventually injected into the substrate of the integrated circuit by the saturating transistor and using this signal for exerting a limiting action on the current which is driven to the base of the power transistor by a dedicated driving circuit. Unlike the prior art antisaturation systems, it is no longer necessary to precisely monitor the operating voltages across the terminals of the bipolar power transistor. A suitable sensing resistance may be integrated conveniently at a distance from the often complex integrated structure of the bipolar transistor. The system of the invention offers numerous advantages and ensures intervention of the antisaturation circuit only when the power transistor has positively reached a state of saturation, but well before any unwanted consequence.
    • 双极功率晶体管的饱和度通过感测由饱和晶体管最终注入到集成电路的衬底中的电流来控制,并且使用该信号对通过功率晶体管的基极驱动的电流施加限制作用 专用驱动电路。 与现有技术的抗饱和系统不同,不再需要精确地监视双极功率晶体管的端子两端的工作电压。 合适的感测电阻可以方便地集成在与双极晶体管的经常复杂的集成结构相距一定距离处。 本发明的系统提供了许多优点,并且仅在功率晶体管正确地达到饱和状态,但在任何不期望的后果之前才能确保抗饱和电路的干预。
