ACS72981LLR Overview
TheAllegro™ACS72981 family of current sensor ICs provides economical and precise solutions forAC or DC current sensing. A 250 kHz bandwidth makes it ideal for motor control, load detection and management, power supply and DC-to-DC converter control, and inverter control. The <2 µs response time enables overcurrent fault detection in safety-critical applications.
