LLC-I2C Click Board

The LLC I2C Click Board™ can be utilized as the level converter for logic signals, which makes it a very useful Click Board™. The topology of this logic level conversion (LLC) circuit is perfectly suited for the bi-directional I2C communication. Although there are some specialised integrated circuits on the market, sometimes it is more convenient to have a simple solution made of just a few passive elements and four MOSFETs. Besides this, MOSFETs can withstand up to 20V across their terminals (12V VGS), and they support far greater currents than typical ICs, making them less likely to fail. The LLC circuitry, also known as the level translator or level shifter, can be used in virtually any application that utilizes the I2C communication protocol and needs matching between the logic voltage levels
