Allegro MicroSystems Expands Isolated Gate Driver Portfolio with Bipolar-Output Power-Thru IC
January 09 2024 - 8:00AM
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 the second product
in its High Voltage Power portfolio. Allegro’s AHV85111 isolated
gate-driver IC adds critical safety features while simplifying the
design of high-power energy conversion systems for e-Mobility and
clean energy applications, including OBC/DCDC, solar inverter and
datacenter power supply.
“Allegro continues to build upon the technology from our
acquisitions in order to expand our High Voltage Power portfolio
aimed at helping designers achieve their efficiency and power
density needs in clean energy and e-Mobility systems,” said Vijay
Mangtani, Vice President and General Manager for High Voltage Power
at Allegro. “The bipolar-output of our latest device improves noise
immunity and significantly simplifies high-frequency
power-converter designs.”
Building upon Allegro’s existing power-thru technology, the
AHV85111 was designed to meet designer demands for a simple,
streamlined and safe solution. The AHV85111 gate driver adds
bipolar-output, a critical feature that significantly improves time
to market by eliminating the need to design a complicated negative
isolated DC power supply and removing unnecessary external
components. Allegro’s newest power-thru solution also adds crucial
safety features that were designed to protect against high
operating temperatures in electric powertrain systems, as well as
reactions to noisy environments that may be present in
microinverters in solar applications, power supply in datacenter
applications or on-board chargers for electric vehicles.
The AHV85111 gate driver packs all the benefits of Allegro’s
power-thru technology, including 10x lower common-mode capacitance,
a 50% smaller footprint, 10x noise reduction and a 50% efficiency
improvement compared to competitor offerings, while also providing
overtemperature protection that further improves the robustness of
system.
