Allegro introduces new isolated gate driver IC, delivering leading power conversion density

July 12, 2023 /SemiMedia/ — Allegro MicroSystems, Inc. just lately introduced the launch of its new Energy-Via remoted gate driver (AHV85110). The primary product launched within the firm’s Energy-Via portfolio; Allegro’s new remoted gate driver creates a single-package answer that drives GaN FETs with as much as a 50% smaller footprint and a 40% effectivity enchancment in comparison with competitor choices.

The worldwide clean-energy motion requires energy system designers in automotive and industrial markets to generate, retailer and use vitality extra effectively. Large-bandgap silicon-carbide (SiC) and gallium-nitride (GaN) field-effect transistors (FETs) provide clear effectivity advantages on the system stage however usually include integration challenges.

A standard gate driver implementation requires each an remoted gate driver and a separate remoted energy provide. When assembled, connections between the motive force, energy supply and FET can add undesirable noise and create pathways of electromagnetic interference (EMI) that may degrade efficiency. Mitigating these results can create design complexity, including time and price to a mission schedule in addition to measurement and weight to an answer.

Allegro’s patent protected, extremely differentiated Energy-Via gate driver (AHV85110) offers engineers and designers entry to new and environment friendly high-power remoted gate driving applied sciences that present a number of system stage advantages. The brand new gate driver is modern and distinctive, combining historically separate elements—the remoted gate driver and the remoted energy provide—right into a single, compact, sturdy bundle. An ideal instance of “much less is extra,” Allegro’s platform minimizes EMI pathways and simplifies integration, leading to quicker time to market, effectivity features, and manufacturing value financial savings.

“Our engineering staff leveraged know-how from our acquisition of Heyday Built-in Circuits to quickly develop the primary gadget in our new Energy-Via portfolio to assist designers obtain their effectivity and energy density targets in clear vitality and e-Mobility techniques,” mentioned Vijay Mangtani, Vice President and Common Supervisor for Excessive-voltage Energy at Allegro MicroSystems. “This new collection of patented, industry-first options allows engineers to construct smaller, more-efficient techniques whereas decreasing time to market and maximizing return on funding.”
