Spasic — Integrated current sensing for spacecraft systems

The PA01

A one-component solution.

An isolated current measurement is built today from an assembly of discrete parts — shunt, isolation barrier, amplifier, conversion and interface — specified, laid out and qualified separately for every design. PA01 replaces it with a single radiation-hardened component.

There is no space-qualified isolated current sensor IC on the market today. PA01 is designed to fill that gap.

◎

Radiation-hardened

Designed for single-event-effect resistance on an SOI platform and hardened to a total ionising dose of 100 krad.

⊞

Galvanically isolated by construction

Hall-effect sensing gives inherent galvanic isolation — no separate isolation barrier needed.

⏻

100% European

A fully European, ITAR-free supply chain — no reliance on US export-controlled parts.

⚠

Fewer parts to qualify

Replacing a multi-component circuit with one qualified device cuts component count, board area, mass and the qualification effort carried by every power system it sits inside.

Where we are

From lab prototype to flight-ready IC

The technology began as a Hall-effect current sensor prototyped and validated in the lab. Spasic was founded in 2026 to design it into a product. Sensor and IC design are underway, backed by ESA Spark and Innofounder funding.

Who we are

A small team, deep in the silicon

Two founders covering a sensor-to-silicon scope that normally takes a substantially larger team, drawn from three DTU research environments.
