SLVS896A–NOVEMBER 2008–REVISED MARCH 2009 16-Channel, 12-Bit PWM LED Driver with 6-Bit Dot Correction 1 FEATURES APPLICATIONS • Monochrome, Multicolor, Full-Color LED 23• 16 Channels, Constant-Current Sink Output Displays • 40-mA Capability (Constant-Current Sink) • LED Signboards • 12-Bit (4096 Steps) Grayscale PWM Control • Display Backlighting • 6-Bit (64 Steps) Dot Correction • LED Power-Supply Voltage up to 17 V DESCRIPTION • V = 3.0 V to 5.5 V CC The TLC59461 is a 16-channel, constant-current sink • Constant-Current Accuracy: LED driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and – Channel-to-Channel = ±1% (typ) 64 constant-current sink steps for dot correction. The – Device-to-Device = ±2% (typ) dot correction adjusts the brightness variations • 30-MHz Data Transfer Rate between LEDs. Both grayscale control and dot • 33-MHz Grayscale PWM Clock correction are accessible via serial interface. The maximum current value of all 16 channels can be set • Extended Serial Interface by a single external resistor. • CMOS Level I/O The TLC59461 has two error information circuits: one • Schmitt Buffer Input for LED open detection (LOD), and a thermal error • Readable Error Information: flag (TEF). LOD detects a broken or disconnected – Continuous Base LED Open Detection LED during display period. TEF indicates an over-temperature condition. (LOD) – Thermal Error Flag (TEF) To allow lower power dissipation, the TLC59461 does not implement the Auto Output Off function available • Noise Reduction: in the TLC5946. – 4-Channel Grouped Delay • Operating Temperature: –40°C to +85°C V V V V LED LED LED LED V CC ¼ ¼ ¼ ¼ ¼ OUT0 OUT15 OUT0 OUT15 OUT SIN SOUT SIN SOUT XERR XERR XERR SCLK SCLK SCLK XLAT XLAT XLAT TLC59461 TLC59461 V V Controller CC CC MODE IC1 ICn MODE MODE BLANK BLANK VCC BLANK VCC GSCLK GSCLK GSCLK XHALF XHALF IN GND GND IREF IREF R R IREF IREF 6 Typical Application Circuit (Multiple Daisy-Chained TLC59461s) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2PowerPAD is a trademark of Texas Instruments, Inc. 3All other trademarks are the property of their respective owners.
