MBI***7 is designed for LED displays with Open-/Short-circuit Detection extension. MBI***7 exploits PrecisionDriveâ„¢ technology to enhance its output characteristics. MBI***7 contains a **-channel shift register and data latches, which convert serial input data into parallel output format. At MBI***7 output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a wide range of VF variations. The excellent output accuracy is within ±3% between channels and within ±6% between ICs. Users may adjust the output current from 5 mA to *0 mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. MBI***7 guarantees to endure maximum *7V at the output port. The high clock frequency, *5 MHz, also satisfies the system requirements of high volume data transmission. MBI***7 also exploits the idea of Share-I-Oâ„¢ technology to extend its performanceï&frac*4;›in addition, MBI***7 is backward compatible with MBI***6 in both electrical characteristics and package aspect. By means of the Share-I-Oâ„¢ technique, an additionally effective function, Open-/Short-circuit Detection, can be added to LED drivers, MBI***7, without adding any extra pin and without changing the printed circuit board originally designed for conventional LED drivers.
