Description
General part information
TLC59291 Series
The TLC59291 is a 8/16-channel constant current sink LED driver. Each channel can be turned on-off by writing data to an internal register. The constant current value of all 16 channels is set by a single external resistor and 128 steps for the global brightness control (BC).
The TLC59291 has six type error flags: LED open detection (LOD), LED short detection (LSD), output leak detection (OLD), reference terminal short detection (ISF), Pre thermal warning (PTW) and thermal error flag (TEF). In addition, the LOD and LSD functions have invisible detection mode (IDM) that can detect those errors even when the output is off. The error detection results can be read via a serial interface port.
The TLC59291 has low quiescent current in normal mode, it also has a power-save mode that sets the total current consumption to 10 µA (typical) when all outputs are off.
