Overview
StarChips Technology SCT2168 V01_01; May/09 8-bit Serial-In/Parallel-Out Constant Current Driver Product Description The SCT2168 serial-interfaced 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 full-scale constant output current from 5mA up to 120mA.
The SCT2168 guarantees each output can endure maximum 17V DC voltage stress.
The built-in shift registers and data latches making the SCT2168 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 SCT2168 will satisfy system which needs high volume data transmission to control the LED display.
Features ‹ 8 constant current sinker with LED power-supply voltage up to 17V ‹ Constant output current : 5 – 120mA@5V, 3 – 80mA@3.
3V ‹ Excellent current regulation to load, supply voltage and temperature ‹ ±1% Current matching between outputs ‹ ±3% Current matching between ICs ‹ Fast output current control: Minimum PWM pulse width = 120ns ‹ All output current are programmed together using a single external resistor ‹ CMOS Schmitt trigger inputs with clock rate up to 25MHz ‹ Operating supply voltage range of 3.
3V to 5.
5V ‹ Built-in power on reset circuit forces all the outputs off while power on ‹ Built-in thermal protection function to prevent damage from over current operation ‹ Gradually 2ns delayed outputs to lower output switching noise ‹ Package: SOP16, SSOP16,SOP16W ‹ Applications: LED Displays, Variable Message Signs, LED Traffic Signs Selector Guide Part SCT2110 SCT2167 SCT2168 SCT2210 SCT2026 SCT2024 Number of Outputs 8 8 8 16 16 16 Max Output Current (mA) 180 60 120 120 90 60 Min PWM Pulse Width (ns) 100 180 120 50 120 180 Supply Voltage (V) 5 3.
