The Texas Instruments TLC5941QPWPRQ1 is an automotive-grade 16-channel constant-current LED driver in a 28-pin HTSSOP package with exposed pad. It operates from a 3 V to 5.5 V supply, supports data rates up to 30 MHz, and drives 16 outputs rated to 61 mA each with up to 17 V of output voltage compliance. The TLC5941QPWPRQ1 is rated for -40°C to 125°C, is lead-free and RoHS compliant, and ships on tape and reel.

Constant-current LED drivers hold each channel at a set current regardless of LED forward-voltage variation, which keeps brightness and colour consistent across an array and removes the need for per-LED ballast resistors. Sixteen channels with 17 V compliance suit LED matrices, backlighting, signage, and multi-string indicator panels driven over a serial interface. The automotive temperature rating to 125°C and the exposed-pad package point at in-vehicle lighting, instrument clusters, and exterior signalling where thermal headroom matters. Automotive lighting suppliers and industrial display OEMs are the typical users.
