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 Bipolar CMOS DMOS (BCD) power-logic process. It provides the drive function for the two discrete power MOSFETs.
Besides 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 T8, T5, PLC, T10, T12, PLL and PLT, for example.
