1. a kind of high-voltage driving circuit, including:

  • Two low voltage input signals;

    Two High voltage output signals, the first signal is flash drive signal, and secondary signal is low side drive signal;

    Cross-conduction prevents circuit, and it is configured as detecting the same of the flash drive signal and the low side both drive signalsShi Qiyong;

    Two level translators, the first level translator produces the flash drive signal, and second electrical level converter is producedThe low side drive signal, the level translator includes:

    Digital Logical Circuits with digital logic signal;

    At least one high-voltage capacitor with the first connection and the second connection, wherein in first connection and the second connectionOne is electrically coupled to the digital logic signal;

    AndCross-linked phase inverter pair, the cross-linked phase inverter is to the defeated of at least one phase inverter with the centeringGo out, the output is electrically coupled to another connection of at least one high-voltage capacitor;

    The output of wherein described cross-conduction prevention circuit is by the flash level translator or the low side level translatorThe output of one reset to closed mode;

    And wherein, the flash level translator further comprises sensing circuit, the sensing circuit can compare by describedCross-linked phase inverter is to the voltage on two nodes in the latch circuit of formation, to improve to flash rail voltageOn quick voltage swing robustness.
