Features

• 8 constant current output channels

• adjustable output current through

external resistor

• serial data in/parallel data out

• output current: 5-90 mA

• 20 MHz clock freq.

Product Description

The MBI5001, utilizing the most advanced Si

technology, is targeted for LED panel display. The

MBI5001 contains CMOS shift registers and latch

functions, converting serial input data into parallel

output format. At output stage, eight regulated current

sources were designed to provide 5-90 mA constant

current for driving the LEDs.

The MBI5001 provides users great flexibility and device performance while using the

MBI5001 in their LED panel system design. Users may adjust the output current of the

MBI5001 through an external resistor R-ext, which gives users flexibility in controlling the

light intensity of LEDs. The MBI5001 guarantees 17V output driving capability, allowing

users to connect more LEDs in series. The high clock frequency, 20 MHz, also satisfies the

system requirement of high volume data transmission.
