IntroductionLP5522TMEV evaluation boards are engineered specifically to enable the functional testing of the LP5522TMEV LED drivers. The evaluation boards are designed to provide a secure connection and easy access to the remaining signals, allowing engineers to quickly inform themselves of the driver’s key characteristics.LP5522TMEV Application FieldLP5522TMEV evaluation boards are ideal for the development, evaluation and demonstration of applications for automotive, industrial, and general purpose lighting solutions. LP5522TMEV solutions are applicable across white and RGBW LED environments and can be configured for standalone operation with the addition of an SPI master interface. The ability to program different breathing, flashing and dimming profiles, as well as the ability to manually step through the various stimuli generated by a single, universal device, is a significant advantage of LP5522TMEV evaluation boards.Furthermore, these LED drivers are commonly used in applications such as police, military, and helicopter-mounted LED lights, automotive exterior lighting systems (dynamic turn signals, brake lights, license plate illumination and headlight clusters) and human-machine interfaces (such as backlight units, keypads and screen icons).LP5522TMEV Working PrinciplesThe LP5522TMEV is a compact and versatile LED driver that combines three channels, an embedded audio converter, and an LVDS DLC link interface. The LP5522TMEV utilizes a creative digital design, allowing the use of the open source Linux platform for the creation of unique features.The microprocessor-controlled digital logic of the LP5522TMEV generates necessary waveforms and control signals for dimming, flashing and breathing effects. Furthermore, the LP5522TMEV utilizes vast array of programming tools associated with the Linux platform to implement numerous complex user-defined color schemes and effects.The LP5522TMEV can be programmed over the SPI and I2C interfaces and supports three independent LED channels. Each channel has eight separate 256-step intensity levels, allowing the output to be finely fine-tuned. The LED drivers also feature a low voltage current sink to efficiently drive LED loads.ConclusionLP5522TMEV evaluation boards are ideal for a variety of LED lighting projects, providing designers with simple and flexible solutions for a wide range of applications. The LP5522TMEV combines three channels, an embedded audio converter, and an LVDS DLC link interface, enabling lighting engineers to create unique features and complex user-defined color schemes and effects. The low voltage current sink further enables the illumination of LED loads with unparalleled efficiency and accuracy.
