GENERAL DESCRIPTION
Output current levels can be easily programmed in 16 steps through AnalogicTech's Simple Serial Control™ (S2Cwire™) interface controlled by a single microcontroller GPIO line. This allows smooth transitions and flexible adjustment of brightness in flash or other lighting modes. The maximum output current can also be set with an external RSET resistor. AAT3171FEATURES
