P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P19
1. 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.
2. Features
n Adjustable preheat time
n Adjustable preheat current
n Current controlled operating
n Single ignition attempt
n Adaptive non-overlap time control
n Integrated high-voltage level-shift function
n Power-down function
n Protection against lamp failures or lamp removal
n Capacitive mode protection
3. Applications
n 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.
