ET6144

Display Drivers Overview

The ET6144 is a constant current LED matrix driver controller designed for high-integration display systems. It supports up to a 12x12 array with 12 independent channels, each delivering up to 50mA output current. The chip features 32-level overall current adjustment and 256-step PWM dimming per pixel for precise grayscale control. Communication utilizes a standard I²C interface with continuous read/write capabilities. An internal RC oscillator operates at a default frequency of 1MHz ±10%, ensuring high refresh rates. Power consumption is minimized with a shutdown current of approximately 2μA. Operating temperatures range from -40°C to +85°C.

Display Drivers Procurement Notes

Verify the specific package variant required for your design, as the ET6144 is available in QFN32, SOP32, and LQFP32 configurations. Confirm that the I²C address settings align with your system architecture. Ensure thermal management strategies accommodate the maximum 50mA per channel output within the specified operating temperature range. Cross-reference the datasheet for register configurations regarding the internal RC oscillator calibration and shutdown modes.

Display Drivers Selection Notes

Select the ET6144 when designing compact LED matrix displays requiring high integration and precise brightness control. This component is optimal for applications demanding low power consumption during standby, evidenced by its microampere shutdown current. Consider this driver for battery-operated devices or space-constrained environments where replacing discrete components with a single IC reduces board complexity. Evaluate the 12-channel limit against your pixel count requirements before finalizing the selection.
