TLC5945 PWP RHB www.ti.com SLVS755–MARCH 2007 16-CHANNEL LED DRIVER WITH DOT CORRECTION AND GRAYSCALE PWM CONTROL FEATURES APPLICATIONS • Monocolor, Multicolor, Full-Color LED • 16 Channels Displays • 12-bit (4096 Steps) Grayscale PWM Control • LED Signboards • Dot Correction • Display Back-lighting – 6 bit (64 Steps) • Drive Capability (Constant-Current Sink) DESCRIPTION – 0 mA to 80 mA The TLC5945 is a 16-channel, constant-current sink, • LED Power Supply Voltage up to 17 V LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness • V = 3.0 V to 5.5 V CC control and a 64-step constant-current sink (dot • Serial Data Interface correction). The dot correction adjusts the brightness • 30-MHz Data Transfer Rate variations between LED channels and other LED • CMOS Level I/O drivers. Both grayscale control and dot correction are accessible via a serial interface. A single external • Error Information resistor sets the maximum current value of all 16 – LOD: LED Open Detection channels. – TEF: Thermal Error Flag The TLC5945 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.
