July 31, 2023 /SemiMedia/ — Allegro MicroSystems, Inc. not too long ago 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 resolution 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. Broad-bandgap silicon-carbide (SiC) and gallium-nitride (GaN) field-effect transistors (FETs) supply clear effectivity advantages on the system degree however usually include integration challenges.

A conventional 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 degree advantages. The brand new gate driver is modern and distinctive, combining historically separate parts—the remoted gate driver and the remoted energy provide—right into a single, compact, strong package deal. An ideal instance of “much less is extra,” Allegro’s platform minimizes EMI pathways and simplifies integration, leading to quicker time to market, effectivity positive aspects, and manufacturing value financial savings.

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

In comparison with different options, Allegro’s differentiated Energy-Via know-how permits engineers to:

  • Present extra energy, extra effectively, utilizing 50% of the design footprint (PCB financial savings).
  • Diminished invoice of supplies (BOM) depend and manufacturing value.
  • Eradicate bootstrap circuits and remoted provides whereas minimizing common-mode capacitance, which reduces EMI filter design efforts and improves general effectivity.
  • Present a dependable, scalable design course of throughout platforms by eliminating the necessity to totally redesign an influence module when working with a number of GaN FET suppliers.
