Current Sensors Procurement Notes

Verify that the specific suffix '530' corresponds to the required ±30 A rating and ±1.25% accuracy level. Confirm the package type is TQFN-12 and that the device meets AEC-Q100 Grade 1 requirements for your target application environment. Ensure the supply voltage matches the selected variant's 3.3 V or 5 V specification.

Current Sensors Selection Notes

Select this component when space-constrained designs require precise AC or DC current measurement in automotive environments. The choice depends on the need for bidirectional sensing, high bandwidth up to 120 kHz, and immunity to external magnetic interference. Consider the OCD feature if immediate fault detection is critical for system safety.
