8-bit Serial-In/Parallel-Out Constant Current Driver

Product Description

The SCT2167 serialꢀinterfaced LED driver sinks 8 LED clusters with constant current to keep the

uniform intensity of LED displays. In applications, an external resistor is used to set the fullꢀscale

constant output current from 5mA up to 45mA. The SCT2167 guarantees each output can endure

maximum 17V DC voltage stress. The builtꢀin shift registers and data latches making the SCT2167

effective solution in driving LED display. The output enable function gates all 8 outputs on and off, and is

fast enough to be used as PWM input for LED intensity control. Since the serial data input rate can be

reached up to 25MHz, the SCT2167 will satisfy system which needs high volume data transmission to

control the LED

Features

8 constant current sinkers with output voltage sustainable to 17V

Constant output current : 5 – 30/45mA@3.3/5V

Excellent regulation to load, supply voltage and temperature

Temperature regulation: ±0.005%/°C

load regulation: ±0.1%/V

line regulation: ±0.5%/V

High current matching accuracy: ±1% between outputs, ±2% between ICs

Fine grayscale response with 180ns PWM pulse width

Dropout voltage 0.5V@20mA, V_DD=5V

CMOS Schmitt trigger inputs with clock rate up to 25MHz @ cascade connection

The constant current value of 8 outputs is set by a single external resistor

Interlaced 30ns delay of output, preventing instant current surge and output bouncing overstress

Builtꢀin power on reset(POR) circuit forces all the outputs off while power on

Package: SSOP16 and SOP16

Applications: LED Displays, Variable Message Signs, Illumination, LED Traffic Signs
