Insights
Allegro MicroSystems has introduced two new sensors, the ACS37220 and ACS37041, which seem to be cutting-edge in terms of efficiency and design simplicity. These sensors provide a streamlined alternative to traditional shunt resistor and op-amp-based solutions by integrating multiple functions into a single package. This integration is significant for design engineers, as it simplifies PCB layout and reduces the number of components required. For those unfamiliar, a shunt resistor is used to measure current by creating a voltage drop that can be easily read, but it often introduces complexities into the design, including heat dissipation and additional board space requirements.
The ACS37220 can handle up to 200A, making it suitable for high-current applications, while the ACS37041, designed for up to 30A, is particularly notable for its compact size. This makes it highly versatile for applications in industrial, automotive and clean energy sectors, where space and efficiency are critical. By reducing the number of components, these new sensors not only lower the bill of materials (BOM) but also mitigate heat generation, which is a common issue in high-power applications.
From a market perspective, Allegro MicroSystems' new products have the potential to significantly strengthen their competitive position in the power and sensing solutions market. Their focus on efficiency and compact design targets key pain points in several high-growth industries. The launch timing is also strategic; the demand for more efficient and smaller components is on the rise, driven by trends in electric vehicles, renewable energy systems and advanced industrial applications.
Investors should note that Allegro’s innovations could lead to increased market share and customer loyalty, as these sensors offer clear advantages over traditional solutions. In particular, the automotive sector, which is aggressively seeking ways to reduce weight and improve energy efficiency, might find these products particularly appealing. However, the financial impact will depend on the company's ability to scale production and successfully market these solutions to their target industries.
New Sensor Solutions Improve Design Efficiency and Reliability with Enhanced Protection
MANCHESTER, N.H., July 08, 2024 (GLOBE NEWSWIRE) -- Allegro MicroSystems, Inc. (“Allegro”) (Nasdaq: ALGM), a global leader in power and sensing solutions for motion control and energy-efficient systems, today announced the launch of its newest high-power current sensor, the ACS37220, as well as the preliminary release of the industry’s smallest leaded magnetic current sensor, the ACS37041. Allegro’s latest solutions enable improved efficiency and reliability, enhanced system protection and a smaller bill of materials compared to discrete shunt resistor and op-amp-based current sensing solutions.
Current shunt solutions require multiple components, take up significant board space and frequently require additional PCB layers and heatsinks to maintain acceptable thermal performance. These factors inevitably add weight and size, as well as design complexities that often lead to increased cost and production time.
Allegro's new sensors address current industry challenges by providing a smaller footprint, higher efficiency, and simpler integration. The ACS37220 is designed to replace high-power sense resistors and can be used for high-current monitoring applications up to 200A. The ACS37041 offers a high level of integration in a compact SOT23-W package and is suitable for a wide range of current sensing applications up to 30A.
“We are excited to bring the ACS37220 and ACS37041 to market. Their small footprint and low-power dissipation provides our customers with a great alternative to traditional shunts,” said Shaun Milano, Business Line Director, Current Sensors at Allegro. “Allegro’s new current sensors demonstrate the company’s commitment to driving innovation and developing highly efficient sensor technology that address the needs of our customers and the design community as a whole.”
Allegro’s new current sensors integrate the functions of the shunt resistor, shunt amplifier and other passive components into a single package. The compact design and efficiency improvements make them ideal low voltage (< 100 V) sensors compared to traditional shunts, while offering the following benefits:
Lower heat dissipation: The lower conductor resistance of integrated magnetic current sensors’ lead frames results in cooler system temperatures.
Simplified design: With fewer components to place and route, PCB layout is more straightforward.
Innovative packaging: Allegro’s integrated sensor solutions integrate the functionality of a traditional shunt resistor circuit into a single package, simplifying component placement and streamlining the design process while minimizing the overall board of materials (BOM).
