The Texas Instruments TLC5917IDR is an 8-channel constant-current LED sink driver designed for various LED lighting applications. It offers 256 programmable global current gain steps for precise analog dimming.
The device provides a constant output current ranging from 3-mA to 120-mA per channel, which remains invariant to load voltage changes. Key features include error flag, fault detection for open or shorted LEDs, and thermal shutdown protection. The TLC5917IDR operates with a 3.3-V or 5-V supply voltage and supports a maximum LED voltage of 20-V.
With a fast response of output current and a 30-MHz clock frequency, this driver is suitable for applications such as LED display systems, LED signage, and general LED lighting. It is available in a 16-SOIC package and supports surface mount.
Additional features include LED short to ground detection and LED short to VLED detection, enhancing system reliability. The output current accuracy between channels is typically less than ±3% maximum, and between ICs, it is less than ±6% maximum.
