Do you believe humanoid robots will become a standard part of your local workforce soon?

Allegro MicroSystems has introduced a new portfolio of 48 V power and sensing integrated circuits tailored for humanoid robotics. The hardware aims to reduce system size and power loss while increasing torque density for complex machines.

Why it matters

Humanoid robots demand components that minimize weight and footprint to function effectively. By consolidating multiple regulators and sensors into smaller chips, Allegro helps manufacturers achieve the performance levels required for advanced robotic mobility.

The A81481 power management IC features a 6 mm by 6 mm package and supports inputs from 12 V to 72 V, while the CT310 TMR sensor delivers sub-degree angular accuracy within a 2 mm by 2 mm footprint. These components are designed to support high-torque robotic joints.

The players

Allegro MicroSystems

This company is a global designer and manufacturer of sensor integrated circuits and application-specific power integrated circuits for the automotive and industrial markets.

Sarcomere Dynamics

This robotics firm specializes in the development of advanced robotic appendages, including dexterous hands and sophisticated grippers.

The details

The new lineup includes the A81481 power management chip, which combines dual buck regulators and five low-dropout outputs to shrink the system footprint. Additionally, the A17802 and A17803 inductive sensors use on-chip filtering to maintain precision even when mechanical air-gaps fluctuate in robotic joints.

Allegro MicroSystems announced the new robotics component portfolio on October 26, 2026.

The Tech Race

This release follows a pattern set by the development of the 24-DoF ARTUS Dex robotic hand, which requires high-density components to achieve human-like dexterity. The integration of these chips marks a shift toward highly optimized, integrated circuit designs that replace bulkier, traditional power management systems.

For developers, these new chips simplify the engineering process by reducing board complexity and lowering material costs. These improvements ultimately support the creation of more affordable and capable humanoid robots for industrial and research applications.

The takeaway

The move toward highly integrated circuits is essential for scaling humanoid robot production. By prioritizing size and torque density, companies like Allegro are enabling the next generation of robots to perform more human-like tasks in smaller, more efficient packages.
