Datasheet
MBI5016
16-bit Constant Current LED Sink Driver
MBI5016 provides users with great flexibility and device
performance while using MBI5016 in their LED panel
system design. Users may adjust the output current of
MBI5016 through an external resistor, R
ext
, which gives
users flexibility in controlling the light intensity of LEDs.
MBI5016 guarantees to endure 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.

Product Description
MBI5016, utilizing the most advanced silicon technology,
is targeted for LED panel display. MBI5016 contains
CMOS shift registers and latch functions, converting
serial input data into parallel output format. At the output
stage, sixteen regulated current sources, implemented in
Bipolar Junction Transistor, were designed to provide
5-90 mA constant current for driving LEDs.

4
/LE
Data strobe input terminal
Serial data is transferred to the output latch
when /LE is high. The data is latched when
/LE goes low.
