SBVS114 – JULY 2008 24-Channel, 12-Bit PWM LED Driver with Internal Oscillator • Noise Reduction: 23 • 24 Channels, Constant Current Sink Output – 4-channel grouped delay to prevent inrush current • 30-mA Capability (Constant Current Sink) • Operating Temperature: –40°C to +85°C • 12-Bit (4096 Steps) PWM Grayscale Control • LED Power-Supply Voltage up to 30 V • V CC = 3.0 V to 5.5 V • Static LED Displays • Constant Current Accuracy: • Message Boards – Channel-to-Channel = ±2% (typ) • Amusement Illumination – Device-to-Device = ±2% (typ) • TV Backlighting • CMOS Logic Level I/O • 30-MHz Data Transfer Rate (Standalone) • 15-MHz Data Transfer Rate (Cascaded Devices, The TLC5947 is a 24-channel, constant current sink SCLK Duty = 50%) LED driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps. PWM • Shift Out Data Changes With Falling Edge to control is repeated automatically with the Avoid Data Shift Errors programmed grayscale (GS) data. GS data are • Auto Display Repeat written via a serial interface port. The current value of all 24 channels is set by a single external resistor. • 4-MHz Internal Oscillator • Thermal Shutdown (TSD): The TLC5947 has a thermal shutdown (TSD) function that turns off all output drivers during an – Automatic shutdown at over temperature over-temperature condition. All of the output drivers conditions automatically restart when the temperature returns to – Restart under normal temperature normal conditions. 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. 2 PowerPAD is a trademark of Texas Instruments, Inc. 3 All other trademarks are the property of their respective owners.
