TLC5917IDR TI LED Driver | 16-SOIC | 8-Channel, Constant Current

Product Overview

The TLC5917IDR is a monolithic, 8-channel, constant-current sink LED driver from Texas Instruments. It is designed for applications requiring high precision and flexibility in LED current control. Each channel can be independently controlled via a serial interface, with output current set by an external resistor. The device operates from a supply voltage of 3V to 5.5V and features a maximum output current of 120 mA per channel. The TLC5917IDR is available in a 16-pin SOIC package, making it suitable for space-constrained designs.
