Characteristics of the IC TFA3354
The TFA3354 is a control- and monitoring-IC to drive an electronic ballast for fluorescent lamps.
The IC actuates the oscillation of a self-oscillating circuit for generation of RF-shaped lamp current by means of
trigger pulses. After successful excitation the oscillation is monitored and further trigger pulses are blocked.
The IC has a timer with low-active output which is activated for one second after supply voltage was applied.
The switching output is effective for pre-heating and ignition systems.
The IC consists an error indication input. In case of error indication the IC stops oscillation. Enquiry cycles
realize interference reduction.
After lamp change the IC starts oscillation again.
The IC protects from overtemperature cutting oscillation. It is programmable when the oscillator circuit shall be
triggered again.
