Allegro MicroSystems Introduces High-Bandwidth Current Sensors Incorporating XtremeSense™ TMR Technology
2024年9月11日 - 9:00PM
Allegro MicroSystems, Inc. (“Allegro”) (Nasdaq: ALGM), a global
leader in power and sensing solutions for motion control and energy
efficient systems, announced today two new XtremeSense™ TMR sensors
that streamline high power density designs, provide space and cost
savings while improving energy efficiency. Allegro’s latest
solutions, CT455 and CT456, offer high-bandwidth and low noise that
enable precise current measurements for AI data center and
automotive powertrain applications.
Today’s prevalent market applications use current sensor modules
that are bulky, intrusive and inefficient. As a result, these
solutions often lack desired accuracy and resolution, and are prone
to potential system failures. These issues can create major design
complexities for engineers that often lead to increased cost and
longer production time.
Allegro’s new current sensors, using XtremeSense TMR technology,
address many of the challenges engineers face by providing superior
magnetic sensitivity, low power consumption and a compact size
compared to other solutions. The CT455 sensor supports two standard
field ranges, allowing it to sense and translate magnetic fields
into a linear analog output voltage, while the CT456 supports a
preprogrammed 6 mT field range. Unlike other market solutions, our
newest TMR sensors offer distinct advantages, as they are designed
to enable smaller, more efficient, high-accuracy current
measurements on PCB or Busbar applications from 80 A up to above
800 A, depending on the configuration, with the best performance
advantages in the 80-200 A range.
“The release of the CT455 and CT456 sensors marks an important
milestone for Allegro as the first TMR products launched since the
acquisition of Crocus,” said Ram Sathappan, Sr. Director, Global
Marketing & Applications at Allegro MicroSystems. “Our newest
current sensors utilizing Allegro’s XtremeSense TMR technology
represent a huge leap forward for high bandwidth current sensing
and monitoring, reinforcing our ongoing commitment towards driving
broader adoption of TMR technology. As a smaller, more efficient
solution, our new TMR current sensors provide significant benefits
over existing market solutions and technologies that our customers
have been looking for.”
Unlike traditional high-power current sensors, Allegro’s newest
TMR sensors offer a contactless, non-intrusive solution that
delivers 1 MHz bandwidth and a 300 ns response time to enable
faster power conversion. For those seeking to maximize power while
minimizing footprint, the compact design, enhanced reliability, and
efficiency improvements of Allegro’s latest sensors make them an
ideal choice, providing the following key benefits:
- Preset magnetic field range of ±6 mT
supports high current measurements
- Low-noise performance improves
measurement sensitivity
- Optimized for rapid changes in
voltage over time (high dv/dt)
- Compact 8-pin SOIC and TSSOP package
