The TLC5954RTQT from Texas Instruments is a 48-channel, constant-current LED driver designed for various lighting applications. This linear driver offers precise current control with individual channel capabilities of 34.9 mA for 32 channels and 24.4 mA for 16 channels, without requiring an external resistor for current setting.
Key electrical features include a supply voltage range of 3.0V to 3.6V and a data transfer rate of 30 MHz. The device supports 3-bit (8 steps) maximum current control and 7-bit (128 steps) global brightness control for each color group, enabling sophisticated lighting effects. Accuracy is high, with channel-to-channel typically ±1% and device-to-device typically ±2%.
Designed for reliability, the TLC5954RTQT operates within an ambient temperature range of -40°C to 85°C. It includes essential features like LED open and short detection (LOD/LSD) and a power-save mode with low consumption. The package is a 56-VFQFN exposed pad, suitable for surface mounting.
This LED driver is well-suited for applications requiring precise control over multiple LEDs, such as signage and general illumination, where accurate brightness and current management are critical.
