TLC59582RTQT TI LED Driver | 56-QFN (8x8) | 48-Channel, 16-Bit PWM

Product Overview

The TLC59582RTQT is a 48-channel, constant-current sink LED driver from Texas Instruments, designed for high-performance display and lighting applications. It integrates a 16-bit (65,536 levels) PWM grayscale control with a 7-bit (128 steps) global brightness adjustment, enabling precise and smooth LED dimming. The device operates over a wide supply voltage range of 3.0V to 5.5V and supports a maximum output current of 35 mA per channel, configurable via an external resistor. The 56-pin QFN (8x8 mm) package offers a compact solution for space-constrained designs.
