ACS37030 & ACS37032 Current Sensors

Allegro MicroSystems ACS37030 and ACS37032 Current Sensors are galvanically isolated and fully integrated high-accuracy current sensor ICs in the LZ fused-lead SOIC-6 packages. These sensors incorporate high operating bandwidth (DC to 5MHz) for fast control loops or for monitoring high-speed switching currents with a typical 40ns response time. Allegro ACS37030 and ACS37032 sensors employ two signal paths that are summed, enabling the sensing of a wide frequency band with a single device. One path involves a Hall-effect element to capture DC and low-frequency current information, while the other uses an inductive coil path to capture high-frequency current information. The internal construction achieves high isolation by magnetically coupling the field generated by current flow in the conductor to the fully monolithic Hall and coil IC.
