Allegro MicroSystems announced the launch of the ACS37002 family of advanced Hall-effect current sensors. The ACS37002 has 400kHz 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. The blend of high electrical performance, advanced packaging, and factory calibration make the ACS37002 a complete solution for many challenging applications (more info).
