MBI5027 General Description

MBI5027 succeeds MBI5026 and is designed for LED displays with open-circuit Error Detection extension. MBI5027 exploits PrecisionDrive™ technology to enhance its output characteristics.

MBI5027 contains a serial buffer and data latches, which convert serial input data into parallel output format. At MBI5027 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.

While MBI5027 is used in their system design for LED display applications, e.g. LED panels, it provides users with great flexibility and device performance. Users may adjust the output current from 5 mA to 90 mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. MBI5027 guarantees to endure maximum 17V at the output port. The high clock frequency, 25 MHz, also satisfies the system requirements of high volume data transmission.

MBI5027 exploits the idea of Share-I-O™ technology to extend its performance;in addition, MBI5027 is backward compatible with MBI5026 in both electrical characteristics and package aspect. With Share-I-O™ technology, users can, without changing the printed circuit board originally for MBI5026, let MBI5027 enter a special function mode, an Error Detection mode, just by setting a sequence of signals on LE(ED1), OE(ED2) and CLK input pins. In the Error Detection mode, MBI5027 detects the status of individual LED connected to MBI5027. The status will be saved in a built-in register. Then, a system controller may read, through SDO pin, the error status from the register to know whether LEDs are properly lit or not. By setting another sequence of signals on LE(ED1), OE(ED2) and CLK input pins, MBI5027 may resume to a Normal mode and perform as MBI5026. In Application Information, users can get detailed ideas about how MBI5027 works in the Error Detection mode.
