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.
