DESCRIPTION
The TLC5923 is a 16 channel constant-current sink
driver. Each channel has a On/Off state and a 128-
step adjustable constant current sink (dot correction).
The dot correction adjusts the brightness variations
between LED, LED channels and other LED drivers.
Both dot correction and On/Off state are accessible
via a serial data interface. A single external resistor
sets the maximum current of all 16 channels.
The TLC5923 features two error information circuits.
The LED open detection (LOD) indicates a broken or
disconnected LED at an output terminal. The thermal
error flag (TEF) indicates an overtemperature
condition.

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.
