16-Channel Constant Current LED Sink Driver

With PrecisionDrive™ technology, MBI5124 is designed for LED displays which require to operate at low currentand to match the luminous intensity of each channel. It provides supply voltage and accepts CMOS logic input at3.3V and 5.0V to meet the trend of low power consumption. MBI5124 contains a serial buffer and data latches whichconvert serial input data into parallel output format. At MBI5124 output stage, sixteen regulated current ports aredesigned to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.Besides, MBI5124 integrates the pre-charge circuit which can relieve the ghosting.

MBI5124 provides users with great flexibility and device performance while using MBI5124 in their system design forLED display applications, e.g. LED panels. It accepts an input voltage range from 3.3V to 5V and maintains aconstant current up from 1mA to 25mA determined by an external resistor, Rext, which gives users flexibility incontrolling the light intensity of LEDs. MBI5124 guarantees to endure maximum 17V at the output port. The highclock frequency, 25 MHz, also satisfies the system requirements of high volume data transmission.


16-Channel PWM Constant Current LED Driver for 1:32 Time-Multiplexing Application

MBI5153 is designed for LED video applications using internal Pulse Width Modulation (PWM) control with selectable 14-bit / 13-bit color depth. MBI5153 features a 16-bit shift register which converts serial input data into each pixel’s gray scale of the output port. Sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs with a wide range of VF variations. The output current can be preset through an external resistor. The innovative architecture with embedded SRAM is designed to support up to 1:32 time-multiplexing applications. Users only need to send the whole frame data once and to store in the embedded SRAM of the LED driver, instead of sending every time when the scan line is changed. It helps to save the data bandwidth and to achieve high grayscale with very low data clock rate. With scan-type Scrambled-PWM (S-PWM) technology, MBI5153 enhances PWM by scrambling the “on” time of each scan line into several “on” periods and sequentially drives each scan line for a short “on” period. The enhancement equivalently increases the visual refresh rate of scan-type LED displays. In addition, the innovative GCLK multiplier technique doubles visual refresh rate.

MBI5153 drives the corresponding LEDs to the brightness specified by image data. With MBI5153, all output channels can be built with 14-bit color depth (16,384 gray scales). When building a 14-bit color depth video, S-PWM technology reduces the flickers and improves the image fidelity.

Through compulsory error detection, MBI5153 detects individual LED for open-circuit errors without extra components. MBI5153 equipped an innovative cross elimination function, and it solves the cross phenomenon induced by failure LEDs. Besides, integrated ghost elimination circuit eases the ghost problems.
