8-bit Constant Current Led Sink Driver With Gain Control

8-bit Constant Current LED Sink Driver With Gain Control MBI5170 succeeds MBI5168 and also exploits PrecisionDrive technology to enhance its output characteristics. Furthermore, MBI5170 uses the idea of Share-I-O technique to make MBI5170 backward compatible with MBI5168 in both package and electrical characteristics and extend its functionality for run-time LED current gain control in LED Display systems. MBI5170 contains an 8-bit Shift register and an 8-bit Output Latch, which convert serial input data into parallel output format. At MBI5170 output stages, eight regulated current ports are designed to provide uniform and constant current sinks with small skew between ports for driving LEDs with a wide range of forward voltage (Vf) variations. Users may adjust the output current from 5 mA to 120 mA with an external resistor Rext, which gives users flexibility in controlling the light intensity of LEDs MBI5170 guarantees to endure maximum 17V at the output ports. Besides, the high Clock frequency up to 25 MHz also satisfies the system requirements of high volume data transmission. By Unkown
