LM9022 Datasheet (National Semiconductor) - Vacuum Fluorescent Display Filament Driver

LM9022, Vacuum Fluorescent Display Filament Driver

The LM9022 is a bridged power amplifier capable of delivering typically 2W of continuous average power into a 10Ω filament load when powered by a 5V power supply.

To conserve power in portable applications, the LM9022’s micropower shutdown mode (IQ = 0.6µA, typ) is activated when VDD is applied to t
