MBI5034

Macroblock Datasheet MBI5034 16-Channel Constant Current LED Sink Driver with Compulsory Open-circuit Detection and Current Gain Features  16 constant-current output channels Small Outline Package Constant output current range: 3~45mA - 3-45mA @ 5V supply voltage - 3-30mA @ 3.3V supply voltage  Compulsory LED open-circuit detection - Open-circuit LEDs can be detected - Full panel, data independent - Flicker-free error detection GF: SOP24L-300-1.00  64-step programmable current gain: from 12.5% to 200%  Excellent output current accuracy, - Between channels: <±1.5% (typ.), and Shrink SOP - Between ICs: <±3% (typ.)  Fast response of output current - Min. output pulse width of OE : 20ns  Staggered delay of output, preventing from current surge  30MHz clock frequency GP: SSOP24L-150-0.64  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, s...
