注意事项 PRECAUTIONS

1 ESD protection: Always follow electrostatic discharge (ESD) control procedures when handling the IC to avoid permanent damage

2 Soldering compliance: Adhere to IPC/JEDEC standards (J-STD-020 for reflow, EN60749-20 for wave soldering, EN60749-15 for iron soldering)

3 Operating limits: Do not exceed absolute maximum ratings (supply voltage ≤7V, reverse supply ≥-0.3V, ambient temp -40°C~150°C, storage temp -55°C~165°C)

4 Linear range: Keep applied magnetic field within linear range to maintain output between10% and90% of VDD

5 Moisture handling: Follow MSL guidelines—MSL3 for TSOT (bake if exposed to moisture), MSL1 for UA

6 EMC design: Use recommended application diagrams for optimal electromagnetic compatibility

7 High-reliability use: Consult Melexis before using in military/medical life-support applications

8 Spec verification: Check latest datasheet from Melexis before system integration
