TLC5941 PWP RHB NT www.ti.com SLVS589D–JULY 2005–REVISED JANUARY 2008 16-CHANNEL LED DRIVER WITH DOT CORRECTION AND GRAYSCALE PWM CONTROL 1 FEATURES APPLICATIONS • Monocolor, Multicolor, Full-Color LED Displays 2• 16 Channels • LED Signboards • 12-Bit (4096 Steps) Grayscale PWM Control • Display Back-Lighting • Dot Correction – 6 Bit (64 Steps) DESCRIPTION • Drive Capability (Constant-Current Sink) The TLC5941 is a 16-channel, constant-current sink, – 0 mA to 80 mA LED driver. Each channel has an individually • LED Power Supply Voltage up to 17 V adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink (dot • V = 3.0 V to 5.5 V CC correction). The dot correction adjusts the brightness • Serial Data Interface variations between LED channels and other LED • Controlled In-Rush Current drivers. Both grayscale control and dot correction are • 30-MHz Data Transfer Rate accessible via a serial interface. A single external resistor sets the maximum current value of all 16 • CMOS Level I/O channels. • Error Information The TLC5941 features two error information circuits. – LOD: LED Open Detection The LED open detection (LOD) indicates a broken or – TEF: Thermal Error Flag disconnected LED at an output terminal. The thermal error flag (TEF) indicates an overtemperature condition. VCC GND SCLK SIN XLAT CNT MODE Constant-Current 1 0 12−Bit Grayscale Driver GS Register OUT0 V IREF PWM Control Max.
