The TLC5952 is a 24-channel, constant-current sink driver. Each channel can be turned on/off with internal register data. The output channels are grouped into three groups of eight channels each. Each channel group has a 128-step global brightness control (BC) function. Both on/off data and BC are writable via a serial interface. The maximum current value of all 24 channels is set by a single external resistor.
The TLC5952 has three error detection circuits: LED open detection (LOD), LED short detection (LSD), and a thermal error flag (TEF). The error detection is read via a serial interface.
