16-Channel, Constant-Current LED Driver with Pre-Charge FET

Check for Samples: TLC59283

FEATURES

•

16-Channel, Constant-Current Sink Output

with On and Off Control

APPLICATIONS

•

Video Displays

•

Constant-Current Sink Capability:

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

Message Boards

•

LED Power-Supply Voltage: Up to 10 V

V_CC= 3 V to 5.5 V

DESCRIPTION

The TLC59283 is a 16-channel, constant-current sink

light-emitting diode (LED) driver. Each channel can

be individually controlled with

communications protocol that is compatible with 3.3-V

or 5-V CMOS logic levels, depending on the

operating VCC. When the serial data buffer is loaded,

a LAT rising edge transfers the data to the OUTn

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.

Constant-Current Accuracy:

a simple serial

–

Channel-to-Channel:

±1.4% (typ), ±3% (max)

–

Device-to-Device: ±2% (typ), ±4% (max)

•

CMOS Logic Level I/O

Data Transfer Rate: 35 MHz

BLANK Pulse Width: 50 ns

Pre-Charge FET for Ghosting Reduction

Grouped Switching Delay for Noise Reduction

Operating Temperature: –40°C to +85°C

Each constant-current output has a pre-charge field-

effect transistor (FET) that can reduce ghosting on

the multiplexing (dynamic) drive LED display. Multiple

TLC59283s can be cascaded together to control

additional LEDs from the same processor.
