The TLC5917IPWRG4 from Texas Instruments is an 8-bit constant-current LED sink driver designed for various LED lighting applications. It provides eight constant-current output channels, with the output current adjustable through a single external resistor, ranging from 3 mA to 120 mA per channel. The output current remains invariant to load voltage changes.
Key electrical features include a 30-MHz clock frequency, 256-step programmable global current gain, and excellent output current accuracy. Channel-to-channel accuracy is typically within ±3%, and between ICs, it's within ±6%. The device supports 3.3-V or 5-V supply voltages and can drive LEDs up to 20 V. It also includes fault detection for open loads, short loads to ground or VLED, and thermal shutdown for overtemperature protection.
This LED driver is available in a 16-TSSOP package suitable for surface mounting. Its applications include general LED lighting, LED display systems, LED signage, automotive LED lighting, white goods, and gaming machines. The integrated features like error flags and fault detection enhance system reliability.
