The is a 16-channel Constant Current LED Sink Driver without LED open detection. 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. The constant-current values are determined by an external resistor RIREF placed between IREF and GND. When BLANK is low, the corresponding output is turned on if the data in the on/off control data latch are "1" and remains off if the data are "0". When BLANK is high, all outputs are forced off.
