IS31FL3293/6/9 LED Drivers

Lumissil's IS31FL3293, IS31FL3296, and IS31FL3299 family of multi-channel LED drivers offer low power consumption, high color resolution, pre-established pattern sequences and space-saving package options.

The IS31FL3293/6/9 devices address the critical challenges of minimal board space and low power consumption required by IoT devices. They consume less than 200 µA when fully operational and only 0.3 µA when placed into sleep mode, making them ideal for applications requiring long battery life. The LED channel currents can sink up to 40 mA with an accuracy of ±5% between channels and between parts.

Device registers can further fine-tune the channel currents. A 6-bit global current register will adjust all the channel currents to a value lower than the default 40 mA. An 8-bit register will individually tune each red, green, or blue LED current for an added level of current control. Furthermore, a 12-bit register can be programmed to output a precise pulse width modulation (PWM) on each LED channel yielding the best possible color mixing for the red, green, and blue LEDs.
