TLC6984RRFR TI LED Driver | 76-VQFN (9x9) | 48-Channel, 16-Bit PWM

Product Overview

The TLC6984RRFR from Texas Instruments is a high-performance 48-channel constant-current LED driver designed for precise brightness control in large-scale LED display and lighting applications. Housed in a compact 76-VQFN (9x9 mm) package, it integrates 16-bit PWM dimming and 8-bit global brightness adjustment, enabling smooth, flicker-free visuals. With a maximum output current of 50 mA per channel and a supply voltage range of 3.0 V to 5.5 V, it supports both RGB and monochrome LED configurations. The device features advanced error detection (LED open/short, thermal shutdown) and a high-speed serial interface (up to 30 MHz) for daisy-chaining multiple ICs, making it ideal for large-format displays, automotive lighting, and industrial signage.

Detailed Technical Specifications

Key Features

• 48 constant-current outputs with 16-bit PWM for high-resolution grayscale
