TLC5952DAP Datasheet PDF - TI

●The TLC5952DAP is a 24-channel constant-current LED Sink Driver with global brightness and LED open short detection. 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. It has three error detection circuits of LED open detection (LOD), LED short detection (LSD) and a thermal error flag (TEF). The error detection is read via a serial interface.
