Abstract
The present invention provides a system for producing high voltage, low power driver circuitry (300) that addresses a number of disparate design requirements. The present invention provides circuitry comprising a voltage supply (308) and an output node (302). A transistor (304) is provided. A first resistive element (312) is coupled to the voltage supply, while a second resistive element (314)—having a resistance value equal to that of the first resistive element—is coupled between a second terminal of the transistor and the output node. A first diode (310) is coupled to the first resistive element and to a first terminal of the transistor. A clamping system (316) is coupled to the transistor, and a current limiting system (318) is coupled to the clamping system.
