The TLC5971RGET from Texas Instruments is a versatile 12-channel LED driver designed for applications requiring precise color and brightness control. It utilizes Enhanced Spectrum PWM technology with 16-bit resolution for grayscale control, allowing for 65,536 steps of adjustment per channel. A 7-bit global brightness control is also available for each color group.
This device supports a direct power supply voltage range of 3V to 5.5V, and its internal linear regulator operates from 6V to 17V, with the LED supply voltage capable of reaching up to 17V. The constant current output is 60mA per channel, with typical channel-to-channel and device-to-device accuracy of ±1%. Data transfer rates up to 20 MHz are supported.
The TLC5971RGET is housed in a 24-VQFN (4x4 mm) package, designed for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. Key features include constant current output, PWM control, and thermal shutdown protection. This driver is well-suited for RGB LED clusters, lamp displays, and other illumination applications.
Features such as auto display repeat function, display timing reset, and selectable GS clock contribute to its usability in various display systems. Unlimited device cascading is also supported, allowing for expansion of the number of controlled LEDs.
