The Texas Instruments TLC5917IPWR is an 8-bit constant-current LED sink driver designed for general LED lighting applications, LED display systems, and LED signage. This device features 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 TLC5917IPWR provides excellent output current accuracy, with less than ±3% variation between channels and less than ±6% between ICs. It operates with a supply voltage of 3.3 V or 5 V and supports a maximum LED voltage of 20 V. The driver includes features such as error flags for LED open, short to ground, and short to VLED detection, along with thermal shutdown protection.
This LED driver has a fast response time and a 30-MHz clock frequency, making it suitable for applications requiring dynamic control. It is available in a 16-TSSOP package, designed for surface mounting. The device also offers 256-step programmable global current gain for analog dimming.
Key features include fault detection, ON/OFF control, and thermal shutdown. The TLC5917IPWR is well-suited for various applications including general LED lighting, LED display systems, LED signage, automotive LED lighting, white goods, and gaming machines.
