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 MOSFETS, in the classical half bridge topology, ensuring 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 preheat 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 normally required bootstrap diode and the zener clamping on Vs, makes the L6574 well suited for low cost applications where few additional components are needed to build a high performance ballast.
