Frequently Asked Questions (FAQs)
How does the ISE-A 800 measure current?
It uses an open-loop Hall-effect sensor to detect magnetic fields around the conductor, enabling isolated measurement without inserting resistance or causing power loss.
Why is the output ratiometric?
The output scales with the 5 V supply, ensuring sensor and ADC track together, which reduces measurement error in systems using the same reference.
How do the different current ranges affect resolution?
Lower ranges (±50 A) provide higher sensitivity, while higher ranges (±200 A) allow measurement of larger currents with lower slope.
What is the benefit of the 200 kHz bandwidth?
It allows accurate sensing of DC, AC, switching ripple, and fast transients used in converters and motor drives.
How fast is the sensor?
≈3 µs response supports real-time feedback and quick detection of overcurrent or switching events.
How should the sensor be mounted for best accuracy?
Keep the primary conductor centered and use non-magnetic hardware to avoid field distortion.
Does it provide isolation?
Yes — the Hall-effect structure provides galvanic separation, and creepage/clearance spacing supports board-level industrial applications.
How stable is it over temperature?
It maintains accuracy across –40 °C to +130 °C, with predictable drift that can be corrected through system calibration.
What system noise considerations apply?
Use short traces and good grounding for the analog output; optional RC filtering improves ADC stability.
When is this sensor preferred over a shunt resistor?
When low power loss, isolation, compact PCB footprint, or wide bandwidth is needed for converters, motor drives, or battery systems.
