The ACS37002 with integrated conductor enables more efficient power conversion in higher frequency switching applications.
Allegro MicroSystems announced the launch of the ACS37002 family of advanced Hall-effect current sensors. The ACS37002 has 400 kHz sensing bandwidth up to 180 A with low offset and better than 1% typical total accuracy over the full –40 °C to 150 °C automotive temperature range. The high speed operation allows customers to operate at higher switching frequencies and design SiC and GaN switching platforms that improve efficiency. The device also employs differential sensing for high immunity to external magnetic field disturbances and is available in three surface-mount package options – optimizing either low-noise, high-isolation, or lowest-in-class internal power loss.
“There is no longer any need to compromise between speed, accuracy and power density,” explains Bob Briano, Product Line Manager at Allegro. “This new product family has it all in easy-to-use surface mount packages. The ACS37002 sets a new standard that design engineers are really going to value.”
The ACS37002 is ideal for demanding green energy industrial and electric vehicle applications, such as:
The blend of high electrical performance, advanced packaging, and factory calibration make the ACS37002 a complete solution for many challenging applications. The plug-and-play feature from Allegro’s factory programming allows designers to achieve a faster time-to-market in the increasingly competitive green energy and high-efficiency automotive markets.
Faster switching improves efficiency in most power conversion applications, which is possible with the increasing adoption of SiC and GaN switches. Allegro created the ACS37002 in direct response to this trend by maximizing the speed of the Hall plates. A higher speed current sensor with high accuracy and DC stability allows for tighter control of the motor or power converter control loop – improving overall efficiency of the system. By enabling faster switching, the ACS37002 also helps designers to reduce overall system size.
Factory-calibrated with a high degree of integration, the ACS37002 also helps designers to reduce system size and reduce time to market by decreasing design cycle time. The ACS37002 integrates a variety of features, including:
The ACS37002 is available in three different SOICW-16 packages:
