Lumissil's introduces the IS31FL3293, IS31FL3296, and IS31FL3299 LED drivers, providing a compact and efficient solution for IoT devices. These multi-channel drivers feature 12-bit color resolution and pre-established pattern sequences, meeting the demands of minimal board space and low power consumption.
With power consumption below 200 µA during operation and a mere 0.3 µA in sleep mode, these drivers are well-suited for applications requiring extended battery life. Each channel can sink currents up to 40 mA with an impressive accuracy of ±5% across all channels and devices.
The device registers offer additional flexibility in current adjustment. A 6-bit global current register allows for fine-tuning of all channel currents below the default 40 mA. An 8-bit register enables individual adjustment of red, green, or blue LED currents, offering precise control over each color. Moreover, a 12-bit register supports programming of pulse width modulation (PWM) on each LED channel, resulting in optimal color mixing for red, green, and blue LEDs.
Lumissil's IS31FL3293, IS31FL3296, and IS31FL3299 LED drivers combine compactness, power efficiency, and advanced color control capabilities, making them an ideal choice for IoT applications with limited space and power constraints.
