Introduction

AI Translation

The TLC5954 is a 48-channel, constant-sink current LED driver. Each channel can be turned on or off by writing data to the internal registers. The output channels (OUTXn) are divided into three groups, with 16 channels in each group. Each channel group (R, G, and B) has a 128-step global brightness control (BC) function. The maximum current values of all 48 channels can be set by an 8-step maximum current control (MC) function. This device has two error flags: LED open detection (LOD) and LED short detection (LSD). The error flags can be read via the serial interface port. This device also has a power-saving mode, which sets the total current consumption to 7 μA (typical) when all outputs are off.

Features

AI Translation
  • 48-channel constant current sink outputs with switch control
  • Current capability:
    • 34.9mA for 32 channels
    • 24.4mA for 16 channels
