MBI5170 is designed for LED displays with Gain Control extension. MBI5170 also exploits PrecisionDrive™ technology to enhance its output characteristics. MBI5170 contains an 8-channel 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. The excellent output accuracy is within 3% between channels and within 6% between ICs. Users may adjust the output current from 5mA to 120mA 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 25MHz also satisfies the system requirements of high volume data transmission.
MBI5170 also exploits Share-I-O™ technology and is backward compatible with MBI5026 in both electrical characteristics and package aspect. By means of the Share-I-O™ technique, an additionally effective function, current gain, can be added to LED drivers, MBI5168, without any extra pins without adding any extra pin and without changing the printed circuit board originally designed for conventional LED drivers.
