Hall Effect Linear Current Sensor, ACS722LLCTR-10AB-T, Allegro

The ACS722LLCTR-10AB-T current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, commercial, and communications systems. Its small package is ideal for space-constrained applications, while also reducing cost through minimized board area. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. The ACS722LLCTR-10AB-T consists of a precise, low-offset, linear Hall-effect sensor circuit with a copper conduction path located near the surface of the die. Current flowing through this copper path generates a magnetic field, which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized by the close proximity of the magnetic field to the Hall transducer.

The ACS722LLCTR-10AB-T is provided in a small, low-profile, surface-mount SOIC8 package. The leadframe is plated with 100% matte tin, making it compatible with standard lead (Pb)-free printed circuit board assembly processes. Internally, the flip-chip device is considered Pb-free; however, the solder bump connections are available in either a Pb-free or high-temperature Pb-based option.
