Allegro MicroSystems announces a series of products for AI data centers and high-performance computing systems that increase power density while helping designers better manage energy use, heat dissipation, and equipment size.
As data centers move toward 800V power distribution and 48V cooling systems to address growing workloads, they require faster, more efficient and more compact semiconductor solutions.
Allegro’s expanded portfolio includes new wide-body higher isolation versions of the ACS37030 and ACS37002 current sensors, the AHV85311 Power-Thru isolated gate driver for silicon carbide power systems, and an improved version of the code-free QuietMotion A89333 48V motor driver.
Together, these products help data center designers:
- Safely monitor and control high voltage 800V power systems
- Reduce energy lost during power conversion
- Fit more power capability into limited board and rack space
- Improve the efficiency and reliability of 48V cooling fans
- Simplify system design and reduce development time
“As AI workloads continue to grow, data center power systems must deliver higher power density without compromising efficiency or reliability,” said Rossi Lo, Head of Research and Development at Acbel, the company that has integrated Allegro’s high-speed current sensors into its latest high-density power solutions for AI data centers to support precise power control and system protection. “As power distribution architectures evolve to support higher power and voltage levels, precise power control and rapid system protection are becoming increasingly critical, with current sensing playing a key role. By working closely with our industry partners and integrating new technologies into our power solutions, Acbel continues to advance our power solutions to meet the evolving requirements of next-generation AI data centers.”
The ACS37030 and ACS37002 current sensors are now available in wide-body packages with a high comparative tracking index (CTI) mold compound enabling 6000V of galvanic isolation for enhanced electrical safety in high-voltage systems. The new sensors provide the fast, accurate current measurement needed to protect power supplies, battery backup units and capacitor banks when AI workloads create sudden changes in power demand.
The compact package also helps customers support 800V systems without increasing the size of the rack power shelf or power supply unit.
Cooling is a major source of energy consumption in AI data centers. Allegro’s augmented QuietMotion A89333 motor driver helps improve the operation of 48V server cooling fans without requiring customers to develop complex motor-control software.
The A89333 features built-in control technology that automatically manages changing airflow conditions and supports the compact fans used in 1U, 2U and 4U servers. This helps system designers improve cooling efficiency, reduce development effort and maintain reliable operation as computing density increases. The same class of products are also designed to support pumps for liquid cooling systems.
