6 V) – 1 mA to 45 mA (VCC > 3.
6 V) • Global Brightness Control (BC): – 6-Bit (64 Steps) with 0% to 100% Range (default is 50%) • LED Power-Supply Voltage: Up to 10 V • VCC: 3.
0 V to 5.
5 V • Constant-Current Accuracy: – Channel-to-Channel: ±1% (typ), ±2.
5% (max) – Device-to-Device: ±2% (typ), ±4% (max) • Data Transfer Rate: 30 MHz • Grayscale Control Clock: 33 MHz • Auto Display Repeat • Auto Data Refresh • Display Timing Reset • Four-Channel Grouped Delay Switching to Prevent Inrush Current • Operating Temperature: –40°C to +85°C APPLICATIONS • LED Video Displays • LED Signboards DESCRIPTION The TLC59482 is a 16-channel, constant-current sink driver.
Each channel has an individually-adjustable, pulse width modulation (PWM) grayscale (GS) brightness control with 65,536 steps.
All channels have a 64-step global brightness control (BC).
BC adjusts brightness deviation with other LED drivers.
GS and BC data are accessible via a serial interface port.
