IS31FL3193D 3-CHANNEL FUN LED DRIVER May 2015 GENERAL DESCRIPTION FEATURES IS31FL3193D 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 I2C interface, automatic address increment In PWM Control mode, the PWM duty cycle of each function output can be independently programmed and 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 Over-temperature protection achieving mixing color breathing or a single color Operating temperature T = 40C ~ +85C A breathing without requiring any additional interface WLCSP-8 (1.6mm1.0mm0.46mm) package activity, thus saving valuable system resources. APPLICATIONS IS31FL3193D is available in WLCSP-8 (1.6mm1.0mm0.46mm) package. It operates from Mobile phones and other hand-held devices for 2.7V to 5.5V over the temperature range of -40C to LED display +85C. LED in home appliances TYPICAL APPLICATION CIRCUIT Figure 1 Typical Application Circuit Note: The IC should be placed far away from the mobile antenna in order to prevent the EMI.
