Frequently Asked Questions
What is the TLC5928DBQ and what are its key specifications?
The TLC5928DBQ is a 16-channel constant-current LED driver IC by Texas Instruments. It supports up to 30mA per output channel, operates with an output voltage up to 17V, and uses a SPI-compatible serial interface for easy microcontroller integration. It is available in a DBQ (SSOP-24) package.
What are the typical applications for the TLC5928DBQ?
The TLC5928DBQ is commonly used in LED display panels, industrial indicator arrays, automotive interior lighting, and consumer electronics backlighting. Its 16 matched constant-current outputs make it well-suited for any application requiring uniform multi-channel LED brightness control.
Can TLC5928DBQ devices be daisy-chained for larger LED arrays?
Yes, the TLC5928DBQ supports daisy-chaining through its SPI-compatible serial data output, allowing multiple devices to be cascaded on a single serial bus. This makes it easy to drive large LED matrices or extended display panels with minimal microcontroller I/O pins.
How is the output current of the TLC5928DBQ programmed?
The output current for all 16 channels is set simultaneously using a single external resistor connected to the R-EXT pin. This resistor programs a reference current that is mirrored to each output, ensuring tight channel-to-channel current matching across the device.
