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.
