The ST2221C-2 is a versatile 16-bit constant current LED driver manufactured by SITI. It is engineered for applications involving LED displays and general LED driving, providing precise current control.
The device features a constant current output that can be set between 5mA and 120mA using a single external resistor. It integrates 16-bit shift registers, latches, and constant current drivers onto a single CMOS chip. The input is compatible with 5V CMOS logic, and it supports a maximum clock frequency of 25MHz for cascade operations.
Available in DIP, SOP, and SSOP packages, the ST2221C-2 is suitable for various mounting requirements. Its design allows for bit-to-bit and chip-to-chip current matching, ensuring consistent performance across multiple channels and devices. The absolute maximum ratings include a supply voltage of up to 7.0V and an output current of up to 120mA.
