Allegro MicroSystems ACS37220 Low-Resistance Current Sensors
Allegro MicroSystems ACS37220 Low-Resistance Current Sensors are housed in a 7-pin QFN package and accurately measure currents up to 200A. The Allegro MicroSystems ACS37220 sensors offer minimal internal conductor resistance (<100μΩ). Using two Hall plates, the devices offer common-mode field rejection and enhanced performance in the presence of external magnetic fields.
Features
- Ultra-low primary conductor resistance, <100μΩ, for high efficiency and high-inrush current capability
- Small footprint, 4mm x 4mm QFN package with wettable flank, suitable for space-constrained automotive applications
- High-bandwidth 150kHz analog output for fast response time in control applications
- Differential Hall sensing rejects common-mode fields
- Patented integrated digital temperature compensation circuitry
- Overcurrent fault output with configurable threshold
- Non-ratiometric output
- 3.3V and 5V supply options
- 100VRMS functional isolation
Applications
- Power management systems
- Battery monitoring systems
- Electric vehicle charging systems
- Motor control systems
