Current Sensors Procurement Notes

Verify the specific suffix (PFF) against the required lead frame configuration and tape-and-reel packaging specifications. Confirm that the AEC-Q100 qualification status meets automotive reliability requirements if applicable. Ensure the selected variant matches the exact sensitivity and operating temperature range defined in the official datasheet to avoid integration issues.

Current Sensors Selection Notes

Select this component when precise measurement of bidirectional currents up to 100A is required in space-constrained designs. The through-hole package facilitates robust mechanical connections in industrial environments. Consider the 20mV/A sensitivity for signal conditioning needs and ensure the system power supply remains stable within the 4.5V to 5.5V range for optimal linearity.

Current Sensors Part Context

This part belongs to the ACS752 family of current sensors, which utilizes advanced Hall effect technology. The SCA designation indicates a specific package type optimized for through-hole assembly. The -100 suffix denotes the 100A current rating, distinguishing it from lower-range variants like the ACS752SCA-050 within the same product line.

Current Sensors Replacement Considerations

Direct substitutes include other Allegro ACS752 series variants with matching sensitivity and package dimensions. Cross-reference pinout configurations carefully when considering alternative manufacturers' Hall effect sensors to ensure compatibility with existing PCB layouts.
