GENERAL DESCRIPTION
The IC is a monolithic integrated circuit for driving electronically ballasted fluorescent lamps, with mains voltages up to 277 V (RMS) (nominal value). The circuit is made in a 650 V BCD power-logic process. It provides the drive function for the 2 discrete power MOSFETs.
Beside the drive function the IC also includes the level-shift circuit, the oscillator function, a lamp voltage monitor, a current control function, a timer function and protections.

FEATURES
• Adjustable preheat time
• Adjustable preheat current
• Current controlled operating
• Single ignition attempt
• Adaptive non-overlap time control
• Integrated high-voltage level-shift function
• Power-down function
• Protection against lamp failures or lamp removal
• Capacitive mode protection.

APPLICATIONS
The circuit topology enables a broad range of ballast applications at different mains voltages for driving lamp types from e.g. T8, T5, PLC, T10, T12, PLL and PLT.
