Constant Current RGB LED Driver with I2C Interface

SGM31030.pdf

The SGM31030 is a 3-channel LED current sink driver featuring a 1MHz I²C-compatible interface. Each LED channel supports an 8-bit DC current scaling register per channel and 6-bit global current scaling register. This architecture also enables up to 256 levels of linear PWM dimming.

The device operates over a supply voltage range of 2.5V to 5.5V, with ultra-low quiescent and shutdown current consumption for power-sensitive applications.

The SGM31030 supports three primary operating modes. PWM & current level mode allows independent output current per channel, facilitating precise color mixing. Simultaneously, the PWM duty cycle for each channel is configurable with 256-step resolution to enable fine-grained brightness and color control. Current level mode provides a continuous current sink output per channel with no PWM modulation, and is suitable for applications requiring steady-state LED illumination. Pattern mode enables per-channel timing adjustment for RGB outputs to maintain predefined output sequence autonomously, without host MCU intervention, thereby offloading timing control and conserving system resources.

The SGM31030 is available in Green UTDFN- 1.5×1.5-8L and UTQFN-1.5×1.5-9AL packages. It operates over an ambient temperature range of -40℃ to +85℃.
