TLC5917QDRQ1 TI LED Driver | 16-SOIC | 8-Channel, Constant Current

Product Overview

The TLC5917QDRQ1 is a monolithic, high-voltage, constant-current sink driver designed by Texas Instruments (TI) for automotive and industrial LED lighting applications. It integrates 8 constant-current sink outputs, each capable of driving up to 120 mA, with a maximum output voltage of 17 V. The device features a serial data interface (SPI-compatible) for easy daisy-chaining and supports a wide supply voltage range from 3 V to 5.5 V. Housed in a 16-pin SOIC package, it is qualified to AEC-Q100 for automotive reliability.
