What are the key features of TLC5940IPWPR?
- 16-channel LED driver with 12-bit grayscale PWM (4096 steps) per channel enables smooth brightness control in LED matrix and display applications
- 6-bit DOT correction per channel compensates for LED-to-LED variation, ensuring uniform brightness across 16 outputs with up to 120 mA per channel
- SPI-compatible serial daisy-chain interface allows cascading multiple TLC5940 ICs to drive large LED arrays with minimal microcontroller GPIO usage
What is TLC5940IPWPR used for?
TLC5940IPWPR is designed for LED display panels, RGB LED matrices, and decorative lighting systems requiring fine-grained per-channel brightness and color control. Its 12-bit grayscale PWM with 6-bit DOT correction enables precise LED calibration in backlighting applications where brightness uniformity across many LEDs is critical. Architectural lighting controllers and wearable LED garments benefit from its daisy-chain capability to scale to 100 or more channels from a single SPI bus.

Frequently Asked Questions
How precisely can TLC5940IPWPR control a multi-LED design?
The driver controls 16 channels with 12-bit grayscale PWM and 6-bit dot correction, enabling calibrated brightness adjustment across a dense LED array.
Which current and interface limits matter during circuit design?
Each of the 16 channels supports up to 120 mA, while the SPI-compatible serial interface permits multiple devices to be daisy-chained for expansion.
For PCB assembly, what package detail should buyers confirm?
TLC5940IPWPR uses a 28-pin HTSSOP package, so procurement and layout teams should verify the thermal pad, footprint, and tape-and-reel ordering suffix.
