Allegro to show new power products at electronica
Allegro MicroSystems has announced a series of new power products designed to improve performance and efficiency across automotive, industrial and data centre applications.
The range, which will be on show at electronica 2024, encompasses 48V motor drivers like the A89212, A89224 and A89333 designed to address the thermal management needs of hybrid electric vehicles and AI Servers. Complementing these drivers is the APM81815, a 48V buck regulator designed for superior EMI performance in dual-voltage hybrid electric vehicles. Rounding out the list of new products is the AHV85311, a high-power isolated gate driver designed to accelerate the development of SiC-based power electronics.
“The new power IC solutions from Allegro represent a significant leap forward in power electronics design," says Ram Sathappan, senior. 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.”
A89212, for instance, is a 48V SoC delivering 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.
The A89224 is optimised for next generation 48V automotive systems. 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.
The A89333 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.
Another new devices is the APM81815 for easy 48V power supply design, 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.
Meanwhile the AHV85311 universal gate driver supports multiple SiC MOSFET vendors, and 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 centre power supplies, solar inverters and industrial motors, it accelerates time to market with superior isolation characteristics and seamless integration for SiC power systems design.
