LED DRIVER

DESCRIPTION

FEATURES

•

16 Channels

The TLC5922 is a constant-current sink driver with 128

steps of adjustable current value (dot-correction). Each

of the 16 channels has an individually controlled

dot-correction and an ON/OFF state. Both the ON/OFF

and dot-correction have their respective modes set via

1 port of serial I/F. The maximum current value of the

constant-current output of all 16 channels is pro-

grammed by a single external resistor. An external

processor programs each of the 16 channels of the

TLC5922 with the desired ON/OFF state and

dot-correction value through a single serial interface.

After all data is loaded, the processor then latches the

information into the TLC5922 and enables the outputs.

Drive Capability

1 Port of Serial Data Input/Output

Fast Switching Output: T_r/ T_f= 10ns (typ)

CMOS Input/Output

30 MHz Data Transfer Rate

Vcc = 3 V to 5.5 V

Operating Temperature = -20°C to 85 °C

32-pin HTSSOP (PowerPAD^TM) Package

The TLC5922 includes two error flags. First is the LED

open detection (LOD) which indicates a broken LED at

an output terminal. The second is a thermal error flag

(TEF) which indicates an over temperature condition.

The TLC5922 has two methods to communicate these

error flags to the external processor. One method is on

a dedicated output pin, XDOWN. The other method is

through the serial data output pin, SOUT.
