(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for xtended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) All voltage values are with respect to network ground terminal.




Description

The TLC5928 is a 16-channel, constant current sink LED driver. Each channel can be turned on/off by writing serial data to an internal register. The constant  current value of all 16 channels is set by a single  external resistor.

The TLC5928 has two error detection circuits: one for LED open detection (LOD) and one for a pre-thermal warning (PTW). LOD detects a broken or disconnected LED and LEDs shorted to GND while the constant current output is on. PTW indicates a high temperature condition.
