Motor Drivers, Controllers Procurement Notes

Verify the specific suffix DWTR indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check RoHS3 compliance status if environmental regulations apply. Validate the 28-SOIC footprint against PCB design requirements. Ensure the operating temperature range meets system thermal constraints.

Motor Drivers, Controllers Selection Notes

Select this component for applications requiring dedicated three-phase BLDC control without external microcontroller complexity. Consider the 10V to 18V supply requirement during power stage design. Evaluate the 28-SOIC package size for board space limitations. Verify compatibility with external switching devices intended for the half-bridge outputs.

Motor Drivers, Controllers Part Context

This part belongs to the UC3625 family of brushless DC motor controllers from Texas Instruments. It shares functional similarities with variants like UC3625N and UC3625Q, differing primarily in packaging and termination style. The DWTR designation specifically denotes the reel-packaged version of the standard DW unit.

Motor Drivers, Controllers Replacement Considerations

UC3625DW is the non-reel equivalent. UC3625N offers a PDIP through-hole alternative. UC3625Q provides a PLCC package option.
