DESCRIPTION
In order to ensure voltage ratings in excess of
600V, the L6574 is manufactured with BCD OFF
LINE technology, which makes it well suited for
lamp ballast applications.

The device is intended to drive two power MOS-
FETS, in the classical half bridge topology, ensur-
ing all the features needed to drive and properly
control a fluorescent bulb.
A dedicated timing section in the L6574 allows the
user set the necessary parameters for proper pre-
heat and ignition of the lamp.
Also, an OP AMP is available to implement closed
loop control of the lamp current during normal
lamp burning.
An integrated bootstrap section, eliminating the nor-
mally required bootstrap diode and the zener clamp-
ing on Vs, makes the L6574 well suited for low cost
applications where few additional components are
needed to build a high performance ballast.
