SBVS152C –DECEMBER 2010–REVISED OCTOBER 2011

16-Channel, Constant-Current LED Driver with 4-Channel Grouped Delay

Check for Samples: TLC59282

FEATURES

APPLICATIONS

•

16 Channels, Constant-Current Sink Output

with On/Off Control

•

Video Displays

Message Boards

Illumination

•

Capability (Constant-Current Sink):

35 mA (V_CC≤ 3.6 V), 45 mA (V_CC> 3.6 V)

•

LED Power-Supply Voltage up to 17 V

V_CC= 3 V to 5.5 V

DESCRIPTION

The 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.

Constant-Current Accuracy:

–

Channel-to-Channel = ±0.6% (typ),

±2% (max)

–

Device-to-Device = ±1% (typ), ±3% (max)

•

Low Saturation Voltage: 0.31 V at 20 mA (typ)

T_A= +25℃, One Channel On
