The Allegro MicroSystems ACS72981LLRATR-050B3 is a linear Hall-effect based current sensor IC designed for precise AC or DC current sensing. It features a low internal conductor resistance of 200 µΩ, resulting in minimal power loss and increased power density.
With a high bandwidth of 250 kHz and a rapid response time of less than 2 µs, this sensor is well-suited for applications requiring fast overcurrent fault detection, such as motor control, load detection and management, power supply control, and inverter control.
The device utilizes differential sensing techniques to minimize output disturbances from common-mode magnetic fields. It is factory-trimmed for accuracy and employs proprietary digital temperature compensation for improved zero output voltage and sensitivity over temperature and lifetime. The sensor is available in a compact 7-pin PSOF package suitable for easy mounting.
This current sensor IC is AEC-Q100 qualified, making it suitable for automotive applications. It operates with 3.3 V and 5 V supply voltages.
