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
