IS31FL3193 3-CHANNEL FUN LED DRIVER December 2014 GENERAL DESCRIPTION FEATURES IS31FL3193 is a 3-channel fun LED driver which One group RGB, single color LED breathing features two-dimensional auto breathing mode. It has system-free pre-established pattern One Shot Programming mode and PWM Control mode 3 independently controlled automatic and for RGB lighting effects. The maximum output current semiautomatic breathing system-free can be adjusted in 5 levels (5mA~42mA). pre-established pattern In PWM Control mode, the PWM duty cycle of each I2C interface, automatic address increment output can be independently programmed and function controlled in 256 steps to simplify color mixing. In One 3 independently controlled outputs of 256 PWM Shot Programming mode, the timing characteristics for steps output current - current rising, holding, falling and off 2.7V to 5.5V supply voltage time, can be adjusted individually so that each output 5 levels programmable output current can independently maintain a pre-established pattern achieving mixing color breathing or a single color Over-temperature protection breathing without requiring any additional interface Operating temperature T = 40C ~ +85C A activity, thus saving valuable system resources. DFN-10 (3mm 3mm) package IS31FL3193 is available in DFN-10 (3mm 3mm). It APPLICATIONS operates from 2.7V to 5.5V over the temperature range of -40C to +85C.
