DESCRIPTION
The TLC5924 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.
Each constant-current output has a pre-charge FET
that enables an improvement in image quality of the
dynamic-drive LED display.
The TLC5924 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 over-temperature
condition.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
