MBI5168CP – TBC

The MBI5168CP is a monolithic, constant-current LED sink driver designed for display applications. Based on the “MACROBLOCK 2003DC” marking, likely a date code, the device features 16 output channels, each capable of sinking up to a specified maximum current, typically in the range of 30-90mA, depending on the specific configuration and external components. The constant-current outputs provide uniform brightness across all connected LEDs, compensating for forward voltage variations. The device likely incorporates a serial interface for programming the output current and enabling/disabling individual channels. Internal shift registers and latches facilitate data transfer and storage. The MBI5168CP is commonly used in LED matrix displays, signage, and other applications requiring precise control of LED current. The availability in tubes (53 units) and reels (105 units) suggests standard packaging for automated assembly processes.
