16通道， 16位， ES -PWM ，完全自我诊断LED驱动器 16-Channel, 16-Bit, ES-PWM, Full Self-Diagnosis LED Driver
The TLC5948A is a 16-channel, constant-current sink LED driver. Each channel has an individually-adjustable, pulse width modulation PWM grayscale GS brightness control with 65,536 steps and 128 steps of constant-current dot correction DC. DC adjusts brightness deviation between channels. All channels have a 128-step global brightness control BC. BC adjusts brightness deviation with other LED drivers. GS, DC, and BC data are accessible with a serial interface port.
The TLC5948A has six error flags: LED open detection LOD, LED short detection LSD, output leakage detection OLD, reference current terminal short flag detection ISF, pre-thermal warning PTW, and thermal error flag TEF. The error detection results can be read with a serial interface port.
