Features:TheTLC5940is a16-channel,constant-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 Channels12bit (4096 Steps) Grayscale PWM ControlDot Correction (6bit/64 steps, storable inm EEPROM)Constant Current Sink Drive Capability 0~60mA ?¡§Vcc 3.6V??LED Power Supply Voltage up to 17VVcc 3-5.5VSerial Data InterfaceControlled In-Rush Current30MHz Data Transfer RateCMOS Level I/O with Clamp Diodes ProtectionError Detection: LED Open, Thermal ErrorApplications:Monocolor, Multicolor, Full-Color LED Displays,LED Signboards,Display Backlighting,General, High-Current LED DriveSpecifications:Model :TLC5940NTNumber of Pins:28Color:BlackNet weight:2 gPackage weight:12 gPackage included:1 x TLC5940NT IC LED Driver PWM control
