Current Sensors Procurement Notes

Verify the specific suffix TU against official Melexis documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard 16-SOIC reflow profiles. Confirm that the ratiometric output configuration matches the system reference voltage requirements. Validate AEC-Q100 qualification status for the intended automotive application environment.

Current Sensors Selection Notes

Select this model for applications requiring high bandwidth up to 300 kHz and precise bidirectional current measurement. The 80 mV/A sensitivity suits systems needing clear signal differentiation. Consider the 16-SOIC footprint for PCB layout constraints. The dual OCD outputs provide hardware-level protection capabilities. Ensure the 5 V supply rail stability aligns with the ratiometric operation mode.
