Infineon Technologies AG Lighting, Ballast Controllers IR2156PBF

The IR2156PBF is a ballast control integrated circuit that combines a high voltage half-bridge gate driver with a programmable oscillator. It features programmable preheat and run frequencies, preheat time, dead-time, and over-current protection, making it suitable for various lighting applications. The device includes comprehensive protection mechanisms against lamp strike failures and filament issues, along with an automatic restart function. It operates with a micropower startup current of 150 ¬µA and has built-in latch immunity and ESD protection. The IR2156PBF is available in both SOICN14 and PDIP14 packages, with a maximum supply voltage of 625V and a junction temperature range of -55¬8C to 150¬8C. This product is designed for industrial applications and is lead-free, meeting MSL3 qualification standards.
