The IS31FL3238 is an 18-channel constant current LED driver with independent PWM control for each channel. It operates from a supply voltage of 2.7V to 5.5V and features an I2C interface with an automatic address increment function. The device allows for 256-step PWM brightness modulation and each channel can be independently scaled by factors of 1, 1/2, 1/3, and 1/4. It includes a software shutdown mode and an SDB pin for hardware shutdown to minimize power consumption.
