Allegro MicroSystems has launched the ACS37002 family of advanced Hall-effect current sensors. The ACS37002 offers 400kHz sensing bandwidth up to 180A with low offset and better than 1% typical total accuracy over the full -40C to 150C automotive temperature range.
The high-speed operation enables customers to perform at higher switching frequencies and design SiC and GaN switching platforms that enhance efficiency. The device also uses differential sensing for high immunity to external magnetic field disturbances. It is offered in three surface-mount package options: optimising either high-isolation, low-noise, 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 device is ideal for demanding green energy industrial and electric vehicle applications, such as solar power inverters, on-board charger power-factor correction, DC-DC converter loop control, and xEV high voltage inverters.
