GENERAL DESCRIPTION
IS31FL3218 is comprised of 18 constant current channels each with independent PWM control, designed for driving LEDs. The output current of each channel can be set at up to 38mA (Max.) by an external resistor. The average LED current of each channel can be changed in 256 steps by changing the PWM duty cycle through an I2C interface.

FEATURES
● 2.7V to 5.5V supply
● I2C interface, automatic address increment
   function
● Internal reset register
● Modulate LED brightness with 256 steps PWM
● Each channel can be controlled independently
● -40°C to +85°C temperature range
● QFN-24 (4mm × 4mm), SOP-24 package

APPLICATIONS
● Mobile phones and other hand-held devices for
   LED display
● LED in home appliances
