Allegro MicroSystems Launches Magnetic Current Sensors for Automotive and Clean Energy Applications
Allegro MicroSystems Revolutionizes Current Sensing with Compact, Integrated Solutions
Allegro MicroSystems (ALGM), a powerhouse in power and sensing solutions, unveils two groundbreaking current sensors: the high-power ACS37220 and the industry's smallest leaded magnetic current sensor, the ACS37041 (preliminary release). These innovative solutions empower engineers to achieve exceptional efficiency, reliability, and system protection, while minimizing design complexity and cost.
Overcoming the Limitations of Traditional Shunt Resistors:
Traditionally, current sensing relied on bulky shunt resistors and operational amplifiers (op-amps). These solutions require:
- Multiple discrete components, increasing board space and complexity.
- Additional PCB layers and heatsinks for adequate thermal management, adding weight and size.
- Lengthy design processes and higher production costs due to complexities.
Allegro's New Era of Integrated Current Sensing:
Allegro addresses these challenges head-on with its new sensor solutions:
- Smaller Footprint: Both the ACS37220 and ACS37041 boast a significantly smaller footprint compared to traditional setups. This translates to lighter, more compact designs.
- Enhanced Efficiency: Lower power dissipation translates to cooler operating temperatures within your system.
- Simpler Integration: By integrating the functionalities of shunt resistors, shunt amplifiers, and other passive components into a single package, Allegro's sensors streamline design and reduce complexity.
Ideal Solutions for Diverse Applications:
- ACS37220: This high-power sensor is designed as a direct replacement for high-power sense resistors, seamlessly integrating into applications requiring high-current monitoring up to 200A.
- ACS37041: This compact sensor housed in a tiny SOT23-W package offers exceptional integration for a broad range of current sensing applications up to 30A.
Benefits Beyond Reduced Size and Complexity:
Allegro's integrated sensors offer additional advantages over traditional shunts:
- Lower Heat Dissipation: The integrated design leads to cooler system temperatures due to the lower conductor resistance of magnetic current sensor lead frames.
- Simplified PCB Layout: With fewer discrete components to manage, PCB layout becomes more straightforward.
- Reduced Bill of Materials (BOM): The innovative packaging integrates the functionalities of multiple components, minimizing the overall number of parts required.
Empowering Innovation with Cutting-Edge Technologies:
Shaun Milano, Business Line Director for Current Sensors at Allegro, emphasizes the company's commitment to driving innovation: "We are excited to bring the ACS37220 and ACS37041 to market... Allegro's new current sensors demonstrate the company's commitment to developing highly efficient sensor technology that addresses the needs of our customers and the design community as a whole."
