Product details

What this Hall sensor does on your board

It measures both AC and DC over a ±22.5 A range with a sensitivity of 100 mV/A and ±0.5% linearity. The 80 kHz bandwidth and 6.5 µs response time suit it for motor-phase monitoring, DC-DC converter output sensing, and overcurrent detection in automotive and industrial power rails.

This lets you reference the sensor output directly to the same supply rail feeding your ADC, eliminating a separate voltage reference and keeping the measurement accurate across supply tolerances.

For a BOM destined for an ECU, battery management system, or motor drive, that grade removes the need for additional screening or derating analysis.

No NRND or last-time-buy notice applies. For volume commitments or date-code requirements, include those in your inquiry.
