SUNNYVALE, CA January 28, 2008 Maxim Integrated Products (Pink Sheets: MXIM) introduces the MAX16816, a high-voltage, programmable, high-brightness (HB) LED driver for automotive and general lighting applications. Far more versatile than competitive devices, the MAX16816 provides many user-programmable features through on-chip nonvolatile EEPROM registers. Using a microcontroller and a single-wire interface, the programming is done either at the factory or by the designer in the field. |
