ACS37220 Current Sensor Compact Carriers

ACS37220 Current Sensor Compact Carrier pinout.

We are offering these breakout boards with support from Allegro Microsystems as an easy way to use or evaluate their ACS37220 Hall effect-based, electrically isolated current sensors with user-configurable overcurrent fault output. The following list details some of the sensor’s key features:

These sensors are the compact versions, which feature smaller 0.7″×0.8″, 2-layer PCBs for integration into more space-constrained applications or for evaluation of the IC’s performance with a smaller PCB area and fewer copper layers for thermal dissipation. Larger versions with a 6-layer PCB are also available with space for larger connectors and thicker wires for the high-current path.

The following table lists the available ACS37220 carrier options:
