Allegro MicroSystems ACS720KLATR-65AB-T Isolated Hall-Effect Current Sensor

Allegro MicroSystems ACS720KLATR-65AB-T Isolated Hall-Effect Current Sensor

ACS720KLATR-65AB-T bidirectional isolated Hall-effect current sensor with a ±65 A optimized range, 20.5 mV/A typical sensitivity and fast and slow fault outputs.

The Allegro MicroSystems ACS720KLATR-65AB-T is a bidirectional current sensor for AC and DC measurement. Its galvanic isolation separates the sensed current path from the output circuit, and its optimized accuracy range extends to ±65 A.

Differential sensing helps reject common-mode magnetic fields. The output voltage tracks current, while integrated temperature compensation supports stable measurement. Fast and slow open-drain fault outputs provide separate responses for short-circuit and overcurrent detection.

This isolated Hall-effect sensor suits motor control, power inverter stages and three-phase motor applications. Its sensing and fault functions in one device can support current monitoring and fault handling in these systems.
