Allegro MicroSystems' sensing innovation at electronica

These advanced sensing products lower system costs, extend battery life and offer reliable performance across a variety of automotive, industrial and consumer applications.  

The new micropower magnetic switches and latches, the APS11753 and APS12753, redefine position sensing with higher sensitivity options for enhanced air gap tolerance,  and ultra-low power consumption using 50% less power than our existing micropower  products. This makes them well suited for challenging battery-powered applications in medical, consumer and industrial markets. 

"We are excited to announce our latest inductive position sensors as we continue to drive innovation in sensing technology,” commented Ram Sathappan, Senior Director, Global Marketing & Applications at Allegro MicroSystems. "Our inductive sensors deliver high accuracy, advanced diagnostics and connectivity options essential for safety-critical traction motors in electric vehicles, while the magnetic switches and latches enable designers to achieve reliable and energy-efficient position sensing in a variety of applications. We’re anticipating a lot of interest in our solutions and look forward to showcasing these innovations at electronica.”  

Key features of the Inductive Position Sensors:

• Precise contactless angle and motor position sensing: Enables dynamic speed and torque control for smoother motion, reduced vibration and energy savings

• Wide temperature range: Maintains consistent performance and stability in extreme temperatures, ensuring reliability in harsh conditions

• Integrated digital compensation and programmable linearity: Enhances accuracy and resolution while offering design flexibility

Key features of the Micropower Magnetic Switches and Latches:

• Ultra-low power sonsumption: Extends battery life, making them ideal for  portable and wireless devices

• Design flexibility: Wide offering of Magnetic sensitivity options provides design flexibility over a broad set of application needs ranging from stray field rejection  to high sensitivity low magnetic field use cases

• Lower total solution sost: Greater magnetic sensitivity options compensate for mechanical misalignments and variations in magnetic field strength allowing for wider airgap variation and total cost savings 

Allegro's latest technologies highlight its commitment to sensing innovation in 2024. Earlier this year, the company inroduced high bandwidth curent sensors (ACS37030 and ASC37032), designed for rapid response and minimal power loss in high-power density Silicon Carbide (SiC) and Gallium Nitride (GaN) systems.

Allegro also expanded its portfolio with the new XtremeSense TMR sensors, the CT455 and CT456, to provide space and cost savings while improving energy efficiency.
