Current Sensors Procurement Notes

Verify the specific suffix ABT against official Melexis documentation to confirm pinout configuration and package variant. Ensure the RE suffix matches the required reel packaging quantity for your production line. Cross-reference the AEC-Q100 qualification status directly with the manufacturer's datasheet to validate automotive grade compliance before integration into safety-critical designs.

Current Sensors Selection Notes

Select this component when a compact TO-92 form factor is required for space-constrained board mounting. The 50 mV/mT sensitivity suits applications requiring moderate gain without excessive amplification noise. Consider the 8 µs response time for dynamic load monitoring. Verify that the 3.135 V minimum supply voltage aligns with your system's power rail availability during low-voltage operation conditions.
