Product Description
With PrecisionDrive™ technology, MBI5124 is designed for LED displays which require to operate at low current
and to match the luminous intensity of each channel. It provides supply voltage and accepts CMOS logic input at
3.3V and 5.0V to meet the trend of low power consumption. MBI5124 contains a serial buffer and data latches which
convert serial input data into parallel output format. At MBI5124 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.
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 for
LED display applications, e.g. LED panels. It accepts an input voltage range from 3.3V to 5V and maintains a
constant current up from 1mA to 25mA determined by an external resistor, Rext, which gives users flexibility in
controlling the light intensity of LEDs. MBI5124 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.

** Operation at the maximum rating for extended periods may reduce the device reliability; therefore, the suggested
junction temperature of the device is under 125°C.

Note: The performance of thermal dissipation is strongly related to the size of thermal pad, thickness and layer
numbers of the PCB. The empirical thermal resistance may be different from simulative value. Users should plan for
expected thermal dissipation performance by selecting package and arranging layout of the PCB to maximize the
capability.

Application Information
Constant Current
To design LED displays, MBI5124 provides nearly no variations in current from channel to channel and from IC to IC.
This can be achieved by:
1) The maximum current variation between channels is less than ±2.5%, and that between ICs is less than ±3%.
2) In addition, the current characteristic of output stage is flat and users can refer to the figure as shown below. The
output current can be kept constant regardless of the variations of LED forward voltages (V F). This performs as a
perfection of load regulation.

Adjusting Output Current
The output current of each channel (IOUT) is set by an external resistor, Rext. The relationship between IOUT and Rext is
shown in the following figure.

Also, the output current can be calculated from the equation:

VR-EXT=1.23V；IOUT=VR-EXT*(1/Rext)x15; Rext =(VR-EXT/IOUT)x15
Where Rext is the resistance of the external resistor connected to R-EXT terminal and VR-EXT is the voltage of R-EXT
terminal. The magnitude of current (as a function of Rext) is around 20mA at 930Ω and 10mA at 1860Ω.

Output Staggered Delay

MBI5124 has a built-in staggered circuit to perform delay mechanism. The 16 output channels are categorized into 2
groups OUT2n and OUT2n  1, and each group outputs current by the staggered sequence, 2ns.

Package Power Dissipation (PD)
The maximum allowable package power dissipation is determined as PD(max)=(Tj–Ta)/Rth(j-a). When 16 output
channels are turned on simultaneously, the actual package power dissipation is
PD(act)=(IDDxVDD)+(IOUTxDutyxVDSx16). Therefore, to keep PD(act)≤PD(max), the allowable maximum output current
as a function of duty cycle is:
IOUT={[(Tj–Ta)/Rth(j-a) ]–(IDDxVDD)}/VDS /Duty/16, where Tj=150°C.

MBI5124 are designed to operate with VDS ranging from 0.4V to 0.8V (depending on IOUT=1~25mA) considering the
package power dissipating limits. VDS may be higher enough to make PD(act) >PD(max) when VLED=5V and
VDS=VLED–VF, in which VLED is the load supply voltage. In this case, it is recommended to use the lowest possible
supply voltage or to set an external voltage reducer, VDROP.
