Allegro MicroSystems Introduces New Isolated Gate Driver IC to Enable Leading Power Conversion Density
11 Luglio 2023 - 1:00PM
Allegro MicroSystems, Inc. (“Allegro”) (Nasdaq: ALGM), a global
leader in power and sensing solutions for motion control and energy
efficient systems, today announced the launch of its new Power-Thru
isolated gate driver (AHV85110). The first product introduced in
the company’s Power-Thru portfolio; Allegro’s new isolated gate
driver creates a single-package solution that drives GaN FETs with
up to a 50% smaller footprint and a 40% efficiency improvement
compared to competitor offerings.
The global clean-energy movement requires power system designers
in automotive and industrial markets to generate, store and use
energy more efficiently. Wide-bandgap silicon-carbide (SiC) and
gallium-nitride (GaN) field-effect transistors (FETs) offer clear
efficiency benefits at the system level but often come with
integration challenges.
A traditional gate driver implementation requires both an
isolated gate driver and a separate isolated power supply. When
assembled, connections between the driver, power source and FET can
add unwanted noise and create pathways of electromagnetic
interference (EMI) that can degrade performance. Mitigating these
effects can create design complexity, adding time and cost to a
project schedule as well as size and weight to a solution.
Allegro’s patent protected, highly differentiated Power-Thru
gate driver (AHV85110) gives engineers and designers access to new
and efficient high-power isolated gate driving technologies that
provide multiple system level benefits. The new gate driver is
innovative and unique, combining traditionally separate
components—the isolated gate driver and the isolated power
supply—into a single, compact,robust package. A perfect example of
“less is more,” Allegro’s platform minimizes EMI pathways and
simplifies integration, resulting in faster time to market,
efficiency gains, and production cost savings.
“Our engineering team leveraged technology from our acquisition
of Heyday Integrated Circuits to rapidly develop the first device
in our new Power-Thru portfolio to help designers achieve their
efficiency and power density goals in clean energy and e-Mobility
systems,” said Vijay Mangtani, Vice President and General Manager
for High-Voltage Power at Allegro MicroSystems. “This new series of
patented, industry-first solutions enables engineers to build
smaller, more-efficient systems while reducing time to market and
maximizing return on investment.”
Compared to other solutions, Allegro’s differentiated Power-Thru
technology enables engineers to:
- Provide more power, more efficiently, using 50% of the design
footprint (PCB savings).
- Reduced bill of materials (BOM) count and production cost.
- Eliminate bootstrap circuits and isolated supplies while
minimizing common-mode capacitance, which reduces EMI filter design
efforts and improves overall efficiency.
- Provide a reliable, scalable design process across platforms by
eliminating the need to fully redesign a power module when working
with multiple GaN FET suppliers.
