Top Features

AEC-Q100 qualified
Differential Hall sensing rejects common-mode stray magnetic fields
Overcurrent FAULT with a Factory Programmable trip range of 50% to 200% of full-scale current
Non-Ratiometric output provides immunity to noisy supplies
Galvanically Isolated:
- QFN package: 120VDC working voltage
- SOIC8 package: UL certified to 2400VRMS, working voltage of 420VDC or 297VRMS
Reduced Power Loss:
- 0.6 mΩ internal conductor resistance on QFN package
- 1.2 mΩ internal conductor resistance on SOIC8 package
Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
Output voltage proportional to AC or DC current
High-bandwidth 120 kHz analog output for faster response times in control applications
Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
3.3 and 5 V single supply operation
Small footprint, low-profile QFN and SOIC8 packages suitable for space-constrained applications
