The L6574 is a high voltage driver designed for lamp ballast applications. It is manufactured with BCD OFF LINE technology to ensure voltage ratings above 600V. The L6574 is capable of driving two power MOS-FETs in a half bridge topology to drive and control a fluorescent bulb. It features a dedicated timing section for pre-heat and ignition of the lamp, as well as a sense op amp for closed loop control or protection. The integrated bootstrap section and clamping on VS make the L6574 suitable for low cost applications.
