# Allegro MicroSystems (ALGM)

Allegro MicroSystems designs magnetic sensor integrated circuits and power semiconductors.

## AI Exposure Score

**55/100, Strategic.** Allegro's current sensors and motor drivers ride the AI server power and cooling buildout, and data center has become its fastest-growing market. Automotive and industrial still dominate revenue, so the thesis depends on content gains per AI rack continuing to outgrow the legacy base.

## What the company does

Allegro MicroSystems designs magnetic sensor integrated circuits and power semiconductors. Automotive and industrial customers are its historic base, using its Hall-effect and TMR sensors and motor driver chips in vehicles, factories, and appliances. As a fabless supplier, it sells through direct and distribution channels to manufacturers worldwide.

Data centers are its fastest-growing market. Current sensors such as the ACS37017 monitor power delivery on AI server boards and accelerator cards, while its motor drivers run the fans and pumps that cool dense GPU racks. Rising power density per rack means more sensing and control content in every new AI server generation.

Founded in 1990 as a spinoff of Sprague Electric's semiconductor business, Allegro is headquartered in Manchester, New Hampshire, employs about 4,250 people, and trades on the NASDAQ.

## Role in the AI buildout

Allegro sits in the Semiconductors layer of the buildout. AI servers draw enormous current, and that power must be measured, regulated, and cooled at every stage. Allegro's current sensors sit on server boards and accelerator cards watching power delivery, while its motor drivers spin the fans and pumps that keep GPU racks within thermal limits. It is a picks-and-shovels play on power density: each jump in accelerator power draw adds sensing and cooling content per rack.

## FAQ

### What does Allegro MicroSystems do?

Allegro designs magnetic sensor chips and power semiconductors, including Hall-effect and TMR current sensors and motor driver ICs. Its chips measure current and control motors in cars, industrial equipment, appliances, and increasingly in AI data center hardware.

### How is Allegro MicroSystems exposed to AI?

Supercycle rates Allegro as Strategic with an AI Exposure Score of 55 out of 100. Data center is its fastest-growing market, tied directly to AI server power and cooling, but automotive and industrial products still dominate revenue.

### What Allegro products serve AI data centers?

The ACS37017 current sensor line targets AI server power electronics, monitoring high-current power delivery on boards and accelerator cards. Its motor driver ICs control the fans and liquid cooling pumps that manage heat in dense GPU racks.

### Who leads Allegro MicroSystems?

Michael Doogue serves as president and chief executive. A long-tenured Allegro engineer and executive, he rose through the company's technology organization before taking the top job, and leads about 4,250 employees from Manchester, New Hampshire.

### Is ALGM a pure play AI stock?

No. Allegro is a Strategic tier stock. Its AI data center content is real and growing quickly, but the company remains primarily an automotive and industrial chip supplier, so the AI story is a rising segment rather than the whole business.
