Description
General part information
TLC5952 Series
The TLC5952 device is a 24-channel, constant-current sink driver. Each channel can be turned on or 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 device has three error detection circuits: LED-open detection (LOD), LED-shorted detection (LSD), and a thermal error flag (TEF). The error detection is read via a serial interface.
