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. 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, Rext, 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.

Pin Description
FUNCTION Ground terminal for control logic and current sink Serial-data input to the shift register Clock input terminal for data shift on rising edge Data strobe input terminal Serial data is transferred to the output latch when /LE is high. The data is latched when /LE goes low. Constant current output terminals Output enable terminal When (active) low, the output drivers are enabled; when high, all output drivers are turned OFF (blanked). Serial-data output to the following SDI of next driver IC Input terminal used to connect an external resistor for setting up output current for all output channels 5V supply voltage terminal
