Product Description
Conditions
IOUT= 3mA ~ 30mA @VDS≧0.8V; VDD= 3.3V
IOUT= 3mA ~ 45mA @VDS≧0.8V; VDD= 5.0V
With PrecisionDrive™ technology, MBI5167 is designed for LED displays which require to be operated at low
current and to match the luminous intensity of each channel. It provides supply voltage and accepts CMOS logic
input at 3.3V and 5.0V to meet the trend of low power consumption. MBI5167 contains a serial buffer and data
latches which convert serial input data into parallel output format. At MBI5167 output stage, sixteen regulated
current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF
variations.
MBI5167 provides users with great flexibility and device performance for LED display applications, e.g. LED panels.
It accepts an input voltage range from 3V to 5.5V and maintains a constant current up from 3mA to 45mA
determined by an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs.
MBI5167 guarantees to endure maximum 17V at the output port. The high clock frequency, 25MHz, also satisfies
the system requirements of high volume data transmission.
