Introduction

AI Translation

The TLC5955 is a 48-channel constant sink current driver. Each channel features an independently adjustable pulse width modulation (PWM) grayscale (GS) brightness control with 65,536 steps and a 128-step constant current dot correction (DC). DC can adjust the brightness deviation between channels. All channels have a 128-step global brightness control (BC). BC adjusts the brightness deviation among the R, G, B color groups. An 8-step maximum current control (MC) selects the maximum output current range for all channels of each color group. The GS, DC, BC, and MC data can be accessed through a serial interface port. The TLC5955 has two error flags: LED open detection (LOD) and LED short detection (LSD). The error detection results can be read using a serial interface port.

Features

AI Translation
  • 48 constant current sink output channels
  • Maximum sink current capability for MC, DC, and BC data: 23.9mA (VCC ≤ 3.6V, MC = 5); 31.9mA (VCC > 3.6V, MC = 7)
  • Grayscale (GS) control: 16-bit (65536 steps) supporting enhanced spectrum or traditional PWM
  • Maximum current (MC) control: 3-bit (8 steps) current range from 3mA to 30mA, with 3 MC settings per color group
  • Dot correction (DC) control: 7-bit (128 steps) ranging from 26.2% to 100%
  • Global brightness control (BC): 7-bit (128 steps) from 10% to 100%, with 3 BC settings per color group
  • LED supply voltage: up to 10V
  • VCC: 3.0V to 5.5V
  • Constant current accuracy — channel-to-channel: ±2% (typical), ±5% (maximum); device-to-device: ±2% (typical), ±4% (maximum)
