ACS71240
Description
The Allegro™ ACS71240 current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, automotive, mercial, and munications applications.
Key Features
- AEC-Q100 automotive qualified
- Integrated shield virtually eliminates capacitive coupling
- Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
- High bandwidth 120 kHz analog output for faster response times in control applications
- Patented integrated digital temperature pensation circuitry allows for near closed-loop accuracy over temperature in an open-loop sensor
- Single supply operation with nonratiometric output at 3.3 and 5 V options
- Overcurrent FAULT available between 50% and 200% IP with 1.5 µs (typ) response time
- Nonratiometric output provides immunity to noisy supplies
- Small footprint QFN-12 with wettable flank and SOIC-8 suitable for space-constrained automotive applications
- 0.6 mΩ (QFN-12) or 1.2 mΩ (SOIC-8) primary conductor resistance for low power loss and high inrush current withstand capability
