NATIONAL SEMICONDUCTOR - LM9022 Vacuum Fluorescent Display Filament Driver Manual
The LM9022 is a National Semiconductor product that is a vacuum fluorescent display filament driver. It is capable of delivering 2 watts of continuous average power into a 10 ohm filament load when powered by a 5V power supply. The LM9022's micropower shutdown mode (IQ = 0.6µA, typical) is activated when VDD is applied to the SHUTDOWN pin, which can be used to conserve power in portable applications. Additional LM9022 features include thermal shutdown protection, unity-gain stability, and external gain set.
