Replace the Shunt
Discover Allegro’s magnetic current sensors to make your design challenges easier
Technology advancements and the evolution of magnetic current sensors over the last two decades have made them a compelling alternative to traditional shunt-based current sensing circuits. With greater efficiency and isolation, higher bandwidths, smaller size and improved overall performance, engineers and designers can quickly and easily integrate these sensors into their electronic systems.
Packaging Innovation: Designers and engineers face the ongoing challenge of creating electronic systems that are both compact and energy-efficient. Allegro's innovative packages, featuring integrated shunt-less sensor solutions, directly address this challenge. By eliminating the need for external shunt resistors and other discrete components, designers and engineers can achieve significant reductions in both component count and overall circuit size while improving efficiency.
- Compact design: The 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 result in cooler system temperatures.
- Simplified design process: By integrating the functionality of a traditional shunt resistor circuit into a single package, Allegro’s technology simplifies component placement and streamlines the design process.
