Allegro MicroSystems Introduces High-Bandwidth Current Sensor Technologies Enabling High-Performance Power Conversion
February 06 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 its new
high-bandwidth current sensors, the ACS37030 and the ACS37032,
which enable high-performance power conversion with GaN and SiC
technologies in electrified vehicles, clean energy solutions and
data center applications.
Current high-power-density GaN and SiC FET charging and power
infrastructures demand high-speed, low-loss devices to ensure
efficiency and reliability. Existing current-sensing solutions have
limited operating ranges, as well as added size and weight that
result in designs with additional components and larger bills of
materials (BOMs).
To address these challenges, Allegro has introduced two
high-bandwidth current sensors – the ACS37030 and ACS37032 –
designed to provide efficiency and high-performance with reduced
design time and board space. They employ a dual signal paths
approach, with one path capturing low-frequency and DC current
using Hall-effect elements and the other path capturing
high-frequency current data through an inductive coil.
“Our ACS37030/2 is the first market solution capable of
responding fast enough for high-speed SiC and GaN protection while
also providing low-frequency content for power-conversion control,”
said Matt Hein, product line manager of current sensors at Allegro.
“Designers can now minimize their system footprint when using GaN
and SiC architectures.”
The compact design, efficiency improvements and cost reductions
of Allegro’s latest current sensors make them suitable for
high-frequency switching in power electronic systems, while
offering the following benefits to designers:
- Efficient and rapid management of high-switching
frequencies and thermal conditions for high voltages and
currents: Delivers fast response times that provide
critical protection and higher efficiency through minimized energy
loss and thermal dissipation.
- Ability to achieve stable and safe control while
reducing electromagnetic interference: Has a 2%
sensitivity error over temperature, while the inductive coil
properties increase the signal-to-noise ratio (SNR) as frequency
increases, minimizing noise and simplifying electromagnetic
compatibility.
- Reduced design footprint, enabling system reliability
and protection: Offered in a compact and efficient
fused-lead SOIC-6 package that can withstand harsh automotive and
industrial environments, enabling reliability and protection.
- Balances cost considerations while minimizing design
complexity: Simplifies designs and facilitates
easy-to-design, cost-optimized, high-power, high-frequency
switching power conversion for GaN and SiC devices.
