DESCRIPTION
The TLC5949 is a 16-channel, constant-current sink
LED driver. Each channel has an individually-
adjustable, pulse width modulation (PWM) grayscale
(GS) brightness control with 4096 steps. All channels
have a 128-step global brightness control (BC). BC
adjusts brightness deviation with other LED drivers.
GS and BC data are accessible with a serial interface
port.
The TLC5949 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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
