16通道, 16位PWM LED驱动器, 7位全局亮度控制 16-Channel, 16-Bit PWM LED Driver with 7-Bit Global Brightness Control
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.
