IS31FL3216 16 CHANNELS LED DRIVER January 2015 GENERAL DESCRIPTION FEATURES The IS31FL3216 is a fun light LED controller with an 2.7V to 5.5V supply audio modulation mode. It can store data of 8 frames I2C interface, automatic address increment with internal RAM to play small animations function automatically. Internal RAM IS31FL3216 can sample the input signal to modulate Modulate LED brightness with 256 steps PWM the intensity of LEDs, or control 8 frames playing by Each channel can be controlled independently internal ADC block. Auto Frame Play Mode with 8 frames The LED current of each channel can be set in 256 8 frames memory for animations steps by adjusting the PWM duty cycle through an I2C Audio Frame Mode with 8 frames interface. 8 channels can be used as GPIO ports. 8 of 16 outputs not used as LED drivers can be used as GPIO ports IS31FL3216 is available in QFN-28 (4mm 4mm). It 8 levels of maximum intensity control operates from 2.7V to 5.5V over the temperature range of -40C to +85C. 8kV HBM ESD Over-temperature protection APPLICATIONS -40C to +85C temperature range Mobile phones and other hand-held devices for QFN-28 (4mm 4mm) package LED display 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.
