Product Description

DESCRIPTION
The TLC5951 is a 24-channel, constant-current sink driver. Each channel has an individually-adjustable,
4096-step, pulse width modulation (PWM) grayscale (GS) brightness control and 128 step constant-current dot correction (DC). The dot correction adjusts brightness deviation between channels and other
LED drivers. The output channels are grouped into three groups of eight channels. Each channel group
has a 256-step global brightness control (BC) function and an individual grayscale clock input.
FEATURES
• 24-Channel Constant-Current Sink Output
• Current Capability: 40 mA
• Selectable Grayscale (GS) Control with PWM: 12-Bit (4096 Step), 10-Bit (1024 Step), 8-Bit (256 Step)
• Three Independent Grayscale Clocks for Three Color Groups
• Dot Correction (DC): 7-Bit (128 Step)
• Global Brightness Control (BC) for Each Color Group: 8-Bit (256 Step)
• Auto Display Repeat Function
• Independent Data Port for GS and BC/DC Data
• Communication Path Between Each Data Port
• LED Power-Supply Voltage up to 15 V
• VCC= 3.0 V to 5.5 V
• Constant-Current Accuracy:
– Channel-to-Channel = ±1.5%
– Device-to-Device = ±3%
• CMOS Logic Level I/O
• Data Transfer Rate: 30 MHz
• 33-MHz Grayscale Control Clock
• Continuous Base LED Open Detection (LOD)
• Continuous Base LED Short Detection (LSD)
• Thermal Shutdown (TSD) with Auto Restart
• Grouped Delay to Prevent Inrush Current
• Operating Air Temperature: –40°C to +85°C
• Packages: HTSSOP-38, QFN-40
APPLICATIONS
• Full-Color LED Displays
• LED Signboards
