From optimising efficiency in automotive applications to simplifying industrial designs as well as enhancing reliability in data centres, Allegro's new power IC innovations enable engineers to design smarter, more efficient systems.

“The new power IC solutions from Allegro represent a significant leap forward in power electronics design," says Ram Sathappan, Sr. Director of Global Marketing & Applications at Allegro MicroSystems. "We're not just meeting the evolving demands of higher voltage and power; we're redefining what's possible. Our customers demand solutions that simplify design, enhance efficiency and lower costs, all of which our new products deliver. We're excited to partner with our customers to shape the future of power electronics and look forward to showcasing our innovative solutions at electronica.”

Key Allegro solutions launching at electronica include:

• A89212: Longer Battery Life and Lower System Costs - This 48V SoC delivers high efficiency and torque at low speeds for power tools, eBikes and other industrial systems. In addition to extending battery life, this sensorless solution improves motor control precision and reduces cost by eliminating external hall sensors. With up to 256K of flash memory and 90V support, it is the first of its kind.
• A89224: Optimised Efficiency for 48V Automotive Systems - This SoC empowers the next generation of 48V automotive systems, optimising fan and pump performance. Advanced motor control libraries maximise efficiency and torque at zero speed for pumps while minimising noise for fans. This translates to reduced power losses, lighter wire harnesses and increased vehicle mileage for OEMs and ODMs. With 256K of flash memory, it offers robust processing power for complex tasks.
• A89333: Increased AI Server Reliability with Code-Free 48V Fan Driver - This motor driver offers code-free integration, reduced power loss and improved thermal management for 48V fans in AI servers. The integrated buck converter is designed to maximise efficiency, extending component life and boosting server reliability. 
• APM81815: Easy 48V Power Supply Design with Fewer Components - This synchronous buck regulator simplifies 48V power regulation, offering a cost-effective solution with minimal design effort and a tiny footprint. Integrated capacitors and 2.2MHz switching frequency achieve industry-leading power density and superior EMI performance, making it ideal for electric power steering, braking, EV powertrains, thermal management, EV charging and robotics.
• AHV85311: Smaller Simpler Design with Higher Efficiency - Supporting multiple SiC MOSFET vendors, this universal gate driver utilising Power-Thru technology offers a compact, efficient solution that simplifies development and enhances overall system performance. By eliminating the need for an external transformer or isolated bias supply, it reduces size, noise and design complexity while boosting efficiency. Ideal for a range of applications, including onboard chargers (OBC), DC-DC converters, data center power supplies, solar inverters and industrial motors, it accelerates time to market with superior isolation characteristics and seamless integration for SiC power systems design.
