Overview
StarChips Technology SCT2027 V01_03; Jun/13 16-bit Constant-Current LED Driver with ModelessTM Error Detection Product Description The SCT2027 is a serial interfaced 16 bit constant current sinker with error detection designed for LED displays and LED lighting applications.
In applications, an external resistor is used to adjust the full scale output current from 5mA up to 90mA.
The serial data are shifted into 16 bit shift register by clock signal.
Input data appear at the SDO output 16 clock cycles later to allow cascading of multiple SCT2027s.
The latch enable input, LA/, loads the 16 bits data of shift register into a 16 bit latch to determine which LEDs are on and off.
The output enable input, OE/ gates all 16 outputs on and off, and is fast enough to be used as PWM input for the LED intensity control.
The SCT2027 combines the SCT2024/6 with ModelessTM technique to detect open load and shorted load errors while driving the LEDs without mode switching*.
With the pin to pin com...
