Preliminary Datasheet
MBI5001
8-bit Constant Current LED Driver
Features
· 8 constant-current output channels
· Output current adjustable through an external resistor
· Serial data in/parallel data out
· Output current: 5-90 mA
· 20 MHz clock frequency
Product Description
MBI5001, utilizing the most advanced Si technology, is
targeted for LED panel display. MBI5001 contains
CMOS shift registers and latch functions converting
serial input data into parallel output format. At the output
stage, eight regulated current sources were designed to
provide 5-90 mA constant current for driving LEDs.

MBI5001 provides users with 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, Rext, which gives users flexibility in controlling the
light intensity of LEDs. MBI5001 guarantees to endure maximum 17V at the output port,
allowing users to connect more LEDs in series. The high clock frequency, 20 MHz, also
satisfies the system requirement of high volume data transmission.
