Texas Instruments TLC5943PWP

The TLC5943 is a 16-channel, constant current sink driver. Each channel is individually adjustable with 65,536 enhanced spectrum pulse-width modulated (PWM) steps controlled by grayscale (GS) data. All output drivers are adjustable with 128 constant sink current steps at same value controlled by brightness control (BC) data. Both GS data and BC data are writable via a serial interface port. The maximum current value of all 16 channels can be set by a single external resistor.

The TLC5943 has two error detection circuits for LED open detection (LOD) and a thermal error flag (TEF). LOD detects a broken or disconnected LED and shorted LED to GND during the display period. TEF indicates an over-temperature condition; when a TEF is set, all output drivers are turned off. When the TEF is cleared, all output drivers are restarted.
