TLC59282 16-Channel, Constant-Current LED Driver



Texas Instruments TLC59282 16-Channel, Constant-Current LED Driver

TI's constant-current sink driver with 4-channel grouped delay

Texas Instruments' TLC59282 is a 16-channel, constant-current sink driver. Each channel can be individually controlled via a simple serial communications protocol that is compatible with 3.3 V or 5 V CMOS logic levels, depending on the operating VCC. Once the serial data buffer is loaded, a rising edge on LATCH transfers the data to the LEDx outputs. The BLANK pin can be used to turn off all OUTn outputs during power-on and output data latching to prevent unwanted image displays during these times. The constant-current value of all 16 channels is set by a single external resistor. Multiple TLC59282s can be cascaded together to control additional LEDs from the same processor.   TLC59282 Datasheet
