DESCRIPTION

•

Serial Data Interface

The TLC5923 is a 16 channel constant-current sink

driver. Each channel has a On/Off state and a

128-step adjustable constant current sink (dot correc-

tion). The dot correction adjusts the brightness vari-

ations between LED, LED channels and other LED

drivers. Both dot correction and On/Off state are

accessible via a serial data interface. A single exter-

nal resistor sets the maximum current of all 16

channels.

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

CMOS Level Input/Output

30 MHz Data Transfer Rate

V_CC= 3.0 V to 5.5 V

Operating Temperature = -20°C to 85 °C

LED Supply Voltage up to 17 V

32-pin HTSSOP (PowerPAD™) Package

Dot Correction

The TLC5923 features two error information circuits.

The LED open detection (LOD) indicates a broken or

disconnected LED at an output terminal. The thermal

error flag (TEF) indicates an overtemperature con-

dition.

– 7 bit (128 Steps)

– individual adjustable for each channel

Controlled In-Rush Current
