Allegro MicroSystems Introduces Advanced Magnetic and Inductive Position Sensing Solutions at Electronica 2024

Allegro MicroSystems (Allegro), a global leader in sensing technology and power semiconductor solutions for motion control and energy-efficient systems, introduced new inductive position sensors and a range of micropower magnetic switches and latches at Electronica 2024. These advanced sensing products reduce system costs, extend battery life, and provide reliable performance in a variety of automotive, industrial, and consumer applications.

The new micropower magnetic switches and latches, the APS11753 and APS12753, redefine position sensing technology by offering higher sensitivity options at wider air gap tolerances and extremely low power consumption, consuming 50 percent less power than our existing micropower products, making the new products ideal for challenging battery-powered applications in the medical, consumer and industrial markets.

“We are pleased to introduce our latest inductive position sensors as Allegro MicroSystems continues to drive innovation in sensing technology,” said Ram Sathappan, Senior Director of Global Marketing and Applications at Allegro MicroSystems. “Our inductive sensors offer high accuracy, advanced diagnostics, and output interface options that are critical for safety-critical traction motors in electric vehicles, while our magnetic switches and latches enable designers to implement reliable and energy-efficient position sensing in a wide range of applications. We anticipate significant interest in these solutions and will be showcasing these innovations at electronica.”

Key features and benefits of the new inductive position sensors (A17802 and A17803):

● Accurate contactless angle and motor position sensing: Enables dynamic control of speed and torque for smoother motion, reduced vibration, and energy savings.

● Wide temperature range: Maintains stable performance and stability in extreme temperatures, ensuring reliability under harsh conditions.

● Integrated digital compensation and programmable linearity: Achieve high accuracy and resolution while providing design flexibility.

Key features and benefits of the new micropower magnetic switches and latches (APS11753 and APS12753):

● Ultra-low power consumption: extends battery life, making it ideal for portable and wireless devices.

● Design Flexibility: A wide range of magnetic sensitivity options are available to meet design flexibility for a range of applications from stray field suppression to high sensitivity and low magnetic fields.

● Reduced total solution cost: Higher magnetic sensitivity options compensate for mechanical misalignment and magnetic field strength variations, allowing for larger air gap variations and saving overall cost

Allegro's latest solutions demonstrate its commitment to sensing innovation throughout 2024. Earlier this year, Allegro launched high-bandwidth current sensors (ACS37030 and ACS37032) designed to achieve fast response and low power loss in high-power density silicon carbide (SiC) and gallium nitride (GaN) systems. These solutions are widely used in electric vehicles, clean energy, and data centers. Allegro also launched sampling resistor replacement current sensors (ACS37220 and ACS37041), which can reduce energy loss and component count compared to traditional sampling resistor-based solutions.
