Allegro MicroSystems Launches New Isolated Gate Driver for Electric Mobility and Renewable Energy Markets
Allegro MicroSystems, a prominent player in delivering power and sensing solutions for efficient motion control and energy systems, recently announced the release of a new member in its High Voltage Power series. The AHV85111 isolated gate-driver integrated circuit, the latest addition to Allegro's lineup, incorporates vital safety enhancements and streamlines the process of designing high-power energy conversion systems utilized in e-Mobility and renewable energy sectors such as on-board chargers/direct current converters, solar inverters, and datacenter power supplies.
"Allegro is diligently leveraging the innovative technologies developed through our acquisitions to enrich our High Voltage Power collection, catering to engineers striving for more effective and compact energy solutions in the clean energy and electric mobility arena," stated Vijay Mangtani, Vice President and General Manager of the High Voltage Power division at Allegro. "The dual-polarity output of this new product strengthens noise resistance and greatly eases the creation of high-frequency power converters."
The AHV85111, which builds on Allegro's proven power-thru technology, is designed to fulfill the demand for an uncomplicated, efficient, and secure option among designers. By introducing a bipolar output, the AHV85111 gate driver significantly reduces the time required to market by doing away with the need for a complex separate negative isolated DC power supply and eliminating superfluous external elements. Moreover, Allegro's cutting-edge power-thru innovation enhances vital safety measures designed to safeguard against elevated operational temperatures found in electric vehicle drivetrains, as well as mitigate the effects of disruptive environments which might be encountered in solar microinverters, datacenter power systems, or electric vehicle chargers.
Equipped with the advantages of Allegro's power-thru prowess, the AHV85111 gate driver offers superior attributes, including a tenfold reduction in common-mode capacitance, a 50% smaller blueprint, noise levels cut by a factor of ten, and a 50% rise in efficiency in contrast to competing products. Furthermore, it incorporates overheating protection, adding to the overall durability and dependability of the system.
