STMicroelectronics L6520/L6521 Ballast Controller Datasheet
The L6520 and L6521 are highly integrated ballast controllers capable of driving both Bipolar Junction Transistors (BJTs) and MOSFETs. They are designed for use in electronic ballasts for fluorescent tubes (TL) and compact fluorescent lamps (CFL), offering features such as preheated and instant start modes, hard switching protection, and choke saturation control. The devices are fully programmable using only resistors and include sophisticated current control circuits for overcurrent and voltage protection.
