Procurement Notes
Verify the specific suffix GF against official MPS documentation to confirm package type and tape/reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the datasheet. Confirm that the TSSOP-28 footprint matches your PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact solution for three-phase BLDC motors is required within a 45 V limit. Consider the 2.5 A continuous output current and thermal dissipation capabilities relative to your load. Evaluate the TSSOP-28 package constraints against available board space and thermal management strategies.
Part Context
This part belongs to the MP6545 series of motor drivers. It serves as a specialized integrated circuit for driving three-phase loads. The family focuses on combining gate drive logic with power MOSFETs to reduce external component count. It targets applications requiring reliable motor control in constrained spaces.
Replacement Considerations
Consult the MPS official cross-reference guide for verified substitutes. Direct replacements must match the TSSOP-28 package and three-phase topology. Verify electrical parameters such as voltage and current ratings align with system requirements.
