MBI5039 16-Channel Constant Current Sink Driver Designed for LED Display systems the MBI5039 contains a 16-bit shift register and 16 pin output latch and features smart error detection functions. Users may adjust the constant output current from 5mA to 90mA with an external resistor which provides flexibility in controlling the LED light intensity. The MBI5039 also sustains up to 17V at the output ports. “In-Message Error Detection” performs the online detection as data-in and error-out sequentially, making it easy to identify the LED open and short errors and report the exact position of the broken LED simultaneously. The “Silent Error Detection” mode features full LED panel detection in order to detect dark pixels in real time, and moreover, the “Silent Error Detection” can diagnose the LED at low current (0.1mA) within a short time period (500ns), in order to avoid flicker or noise on the LED panel. |

| MBI5030 16-Channel PWM Embedded LED Driver Designed for LED video applications the 16-Channel MBI5030 and MBI5031 drivers use scrambled PWM technology an enhancement to increase the visual refresh rate. These drivers provide 16 constant current output channels to provide uniform and constant current sinks for driving LEDs with a wide range of Vf variations. Features include: Open circuit detection to detect individual LED errors, over temperature warning and programmable output current gain. MBI5030 Pdf |

| MBI5026 16-Bit Constant Current LED Driver DMBI5026 exploits PrecisionDriveT technology to enhance its output characteristics. This device contains a serial buffer and data latches which convert serial input data into a parallel output format. At output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large 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 90 mA through an external resistor, which gives users flexibility in controlling the light intensity of the LEDs. The MBI5026 guarantees to endure a maximum 17V at the output port. The high clock frequency of 25 MHz , also satisfies the system requirements of high volume data transmission. |
