Product Information

Description

The Texas Instruments TLC5944 is a 16-channel, constant-current LED driver that is capable of driving up to 60 mA per channel. The TLC5944 has several features including 6-bit Dot Correction, 12-bit grayscale PWM dimming, Pre-Charge FET, LED failure and overtemperature detection. This EVM contains three TLC5944 integrated circuits (IC) connected in series. The three ICs drive 16 light-emitting diodes (LED), each having a red, green, and blue LED in the same package. The EVM is also configured to demonstrate LED multiplexing, which is connecting more than one LED to an LED driver output. The EVM demonstrates multiplexing by connecting an additional row of red LEDs to one of the LED driver ICs. The practice of multiplexing LEDs often generates a phenomenon known as Ghosting. This phenomenon is also called Phantom Noise or Spike Noise. Ghosting occurs when an LED is programmed to be off, but is visually illuminated. The LED is illuminated because of stray currents flowing through it that are generated by switching the rows of LEDs in and out of the circuit, stray board capacitance, and mismatches in diode forward voltages. The TLC5944 contains Pre-Charge FETs that shunt these currents around the LEDs so they do not produce light. The EVM GUI software allows the user to easily demonstrate multiplexing both with and without the Pre-Charge FETs to see the ghosting effect.
