IS31FL3196 6-CHANNEL LIGHT EFFECT LED DRIVER November 2017 GENERAL DESCRIPTION FEATURES IS31FL3196 is a 6-channel light effect LED driver 2.7V to 5.5V supply voltage which features two-dimensional auto breathing mode I2C interface and an audio modulated display mode. It has One Shot Two groups RGB, single color LED breathing Programming mode and PWM Control mode for RGB system-free pre-established pattern lighting effects. The maximum output current can be 6 independently controlled automatic and adjusted in 8 levels (5mA~40mA). semiautomatic breathing system-free In PWM Control mode, the PWM duty cycle of each pre-established pattern output can be independently programmed and 6 independently controlled outputs of 256 PWM controlled in 256 steps to simplify color mixing. In One steps Shot Programming mode, the timing characteristics for 8 levels programmable output current output current - current rising, holding, falling and off Audio mode with AGC function time, can be adjusted individually so that each output Cascade for the synchronization of chips can independently maintain a pre-established pattern Over-temperature protection achieving mixing color breathing or a single color breathing without requiring any additional interface QFN-20 (3mm 3mm) package activity, thus saving valuable system resources. APPLICATIONS The IS31FL3196 includes an audio modulated display mode, wherein the brightness of LED can be Mobile phones and other hand-held devices for modulated by audio signal. There is a cascade pin for LED display the synchronization of two chips. LED in home appliances IS31FL3196 is available in QFN-20 (3mm 3mm). It operates from 2.7V to 5.5V over the temperature range of -40C to +85C.
