Product Description
MBI5168 is designed for LED display applications. As an enhancement of its predecessor, MBI5001, MBI5168
exploits PrecisionDrive™ technology to enhance its output characteristics. MBI5168 contains a serial buffer and
data latches, which convert serial input data into parallel output format. At MBI5168 output stage, eight regulated
current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of Vf
variations.
MBI5168 provides users with great flexibility and device performance while using MBI5168 in their system design
for LED display applications, e.g. LED panels. Users may adjust the output current from 5 mA to 120 mA through
an external resistor R_ext, which gives users flexibility in controlling the light intensity of LEDs. MBI5168 guarantees
to endure maximum 17V at the output ports. The high clock frequency up to 25 MHz also satisfies the system
requirements of high volume data transmission.
