Discover Allegro’s Magnetic Current Sensors to Enhance Your Designs
Integrated shunt-less sensor solutions
Advancements in magnetic current sensors over the past two decades have made them a compelling alternative to traditional shunt-based current sensing circuits. With greater efficiency, isolation, higher bandwidths, smaller size, and improved overall performance, engineers and designers can seamlessly integrate these sensors into their electronic systems.
Allegro's innovative packages feature integrated shunt-less sensor solutions, addressing the challenge of creating compact and energy-efficient electronic systems. By eliminating the need for external shunt resistors and other discrete components, designers can achieve significant reductions in component count and overall circuit size while enhancing efficiency.
Key Benefits
- Compact Design: Integrated magnetic current sensors are significantly smaller, saving valuable board space and reducing the number of components on the bill of materials.
- Lower Heat Dissipation: The lower conductor resistance of integrated magnetic current sensors’ lead frames results in cooler system temperatures.
- Simplified Design Process: Allegro’s technology integrates the functionality of a traditional shunt resistor circuit into a single package, simplifying component placement and streamlining the design process.
