64  Schmitt trigger input Product Description MBI5034 is an enhanced 16-channel constant current LED sink driver with smart error detection and output current gain.
MBI5034 succeeds MBI5026 and also exploits PrecisionDrive™ technology to enhance the output characteristics.
Furthermore, MBI5034 adopts Share-I-O™ technology to be backward compatible with MBI5026, MBI5036 and MBI5039 in pin definition and has the functionality for compulsory LED open-circuit detection and current gain control in LED display systems.
MBI5034 contains a 16-bit shift register and a 16-bit output latch, which convert serial input data into parallel output format.
At MBI5034 output stages, sixteen regulated current ports are designed to provide uniform and constant current sinks with small skew between ports for driving LEDs within a wide range of forward voltage (VF) variations.
Users may adjust the output current from 3mA to 45mA with an external resistor Rext, which provides users flexibility in controlling the light intensity of LEDs.
MBI5034 guarantees to endure maximum 17V at the output ports.
Besides, the high clock frequency, up to 30MHz, also satisfies the system requireme...
