With PrecisionDrive™ technology, MBI5024 is designed for LED displays which require to operate 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. MBI5024 contains a serial buffer and data latches which convert serial input data into parallel output format. At MBI5024 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. The excellent output accuracy is within ±3% between channels and within ±6% between ICs. MBI5024 accepts an input voltage range from 3V to 5.5V and maintains a constant current up from 3 mA to 45 mA determined by an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. MBI5024 guarantees to endure maximum 17V at the output port. The high clock frequency, 25 MHz, also satisfies the system requirements of high volume data transmission. |
