LM9022

Vacuum Fluorescent Display Filament Driver

General Description

The LM9022 is a bridged power amplifier capable of deliv-

ering typically 2W of continuous average power into a 10Ω

filament load when powered by a 5V power supply.

Key Specifications

n I_DDduring shutdown

0.6µA (typ)

n Thermal Shutdown Protection

To conserve power in portable applications, the LM9022’s

micropower shutdown mode (I_Q= 0.6µA, typ) is activated

when V_DDis applied to the SHUTDOWN pin.

Features

n No transformers required

n SO or DIP packaging

Additional LM9022 features include thermal shutdown pro-

tection, unity-gain stability, and external gain set.

Applications

n VCR/DVD Displays

n RADIO/TUNER Displays

Typical Application T_A= 25˚C, V_DD= 5V, unless otherwise specified.
