Allegro MicroSystems, Inc. is a global leader in power and sensing solutions. They have launched the ACS37100. This is the first magnetic current sensor on the market with a 10 MHz bandwidth. This innovative sensor uses Allegro’s XtremeSense™ TMR (Tunneling Magnetoresistance) technology. It provides accurate current measurements. These are vital for the proper operation of wide bandgap (WBG) power electronics.
Enhancing Performance in High-Frequency Applications
The ACS37100 is designed for quick switching with GaN (Gallium Nitride) and SiC (Silicon Carbide) FETs. It has a response time of 50 ns and 26 mA RMS noise over a 10 MHz bandwidth. This helps with accurate current sensing. It’s important for stable control loops in fast-switching applications. Its 5 kV reinforced isolation lasts for 60 seconds, per UL 62368-1. This feature ensures reliable performance in tough conditions.
The ACS37100 has a very low internal conductor resistance of 1.2 mΩ. This leads to less energy loss, making it more efficient and reliable. Its automotive-grade temperature range of -40°C to +150°C makes it perfect for many uses. This covers electric vehicles, clean energy systems, and AI power supplies for data centers.
Implications for the Energy and Power Industry
The ACS37100 is a big step forward in energy and power, especially for WBG power electronics. The industry is moving toward efficient, compact power solutions. So, high-performance current sensing is more important than ever. The ACS37100 helps system designers use GaN and SiC FETs effectively. This boosts power density and efficiency. It helps with electric vehicle charging, renewable energy systems, and AI data center power supplies.
