About
About Allegro MicroSystems
Allegro MicroSystems is a semiconductor supplier whose magnetic sensing, motion-control and power-management devices serve automotive, industrial and robotics equipment. Its robotics offering covers position measurement for motors and joints, compact angle sensing for hands and fingers, and power conversion and diagnostics within tightly packaged machines. The company is based in Manchester, New Hampshire, and trades on Nasdaq as ALGM.
For humanoid designs, Allegro combines inductive joint-position sensors with Hall-effect and tunnelling-magnetoresistance devices, motor and gate drivers, and a 48V power-management architecture. Its A81481 integrates voltage regulation and safety diagnostics, while the A17802 and A17803 address position measurement around high-torque joints. A collaboration with Sarcomere Dynamics covers integrating Allegro electronics into the Scorpion gripper and extending that work to a future ARTUS Dex hand. Samples and evaluation support accompany the robotics component offering.

Timeline
Events
- 2026-10-20 - Product Launch - Allegro MicroSystems expands humanoid sensing and 48V power portfolio
The A81481 integrates dual buck regulators, five LDO outputs and ASIL-D-capable diagnostics in a 6×6 mm package. A17802/A17803 inductive sensors target high-torque joints; CT310 TMR and A33023 Hall-effect sensors address compact joints and fingers. Sarcomere Dynamics is integrating Allegro controllers, sensors and power ICs into its Scorpion gripper, with an ARTUS Dex 24-DoF hand extension planned.
Source - 2023-10-31 - Acquisition - Allegro MicroSystems completes Crocus Technology acquisition
The closing announcement valued the transaction at $420 million in cash, subject to customary working-capital adjustments. Financing combined cash on hand with a new seven-year $250 million senior secured term loan. Crocus’s TMR technology expands Allegro’s magnetic sensing portfolio for electrification, clean energy and automation.
