| Features: TheTLC5940is a16-channelconstant-current sink LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink (dot correction).The dot correction adjusts the brightness variations between LED channels and other LED drivers. The dot correction data is stored in an integrated EEPROM. Both gray scale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels. The TLC5940 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an overtemperature condition. 16 Channels 12bit (4096 Steps) Grayscale PWM Control Dot Correction (6bit/64 steps storable inm EEPROM) Constant Current Sink Drive Capability 0~60mA (Vcc <3.6V) 0~120mA (Vcc > 3.6V) LED Power Supply Voltage up to 17V Vcc 3-5.5V Serial Data Interface Controlled In-Rush Current 30MHz Data Transfer Rate CMOS Level I/O with Clamp Diodes for Protection Error Detection: LED Open Thermal Error Applications:Monocolor Multicolor Full-Color LED DisplaysLED SignboardsDisplay Backlighting General High-Current LED Drive Specifications: Model :TLC5940NT Number of Pins:28 Color:Black Net weight:2 g Package weight:12 g Package included: 1 x TLC5940NT for IC LED Driver PWM control |
