5 V • Constant Current Accuracy – Channel-to-Channel = ±1%(Typ), ±3%(Max) – Device-to-Device = ±1%(Typ), ±2%(Max) • Data Transfer Rate: 25 MHz • Gray Scale Clock: 33 MHz • Pre-Charge FET to Avoid Ghosting Phenomenon • Enhanced Circuit for Caterpillar Cancelling • Low-Grayscale Enhancement • LED Open Detection (LOD) • Thermal Shut Down (TSD) • Operating Temperature: –40°C to 85°C 2 Applications • LED Video Displays with Multiplexing System • LED Signboards with Multiplexing system • High Refresh Rate & High Density LED Panel 3 Description The TLC59581/82are 48-channel constant-current sink drivers.
Each channel has an individuallyadjustable, 65536-step, pulse width modulation (PWM) grayscale (GS) brightness control.
The TLC59581 can support 32-multiplexing while TLC59582 can support 16-multiplexing.
The output channels are divided into three groups.
Each group has a 512-step color brightness control (CC).
CC adjusts brightness control between colors.
The maximum current value of all 48 channels can be set by 8-step global brightness control (BC).
BC adjusts brightness deviation between LED drivers.
GS, CC and BC data are accessible through a serial interface port.
See application note Build High Density, High Refresh Rate, Multiplexing LED Panel with TLC59581, SLVA744.
