Current Sensors for IoT

Aceinna (formerly Memsic) Isolated, Bi-Directional Current Sensors use AMR magnetic sensing technology to provide the best accuracy, bandwidth, and dynamic range available in low-loss, single chip current sensing solutions.

Aceinna is a spin-off of Memsic Inc. a world leader in MEMS sensor technology.

Aceinna is applying its leadership and expertise in Anisotropic Magneto Resistive (AMR) magnetic sensing to AC and DC current sensing.

Devices feature bi-directional current sensing through a fully isolated low impedance current path.  These AMR based current sensors are easily scaled for small or large current ranges.

Applications includes (but not limited): Server, Telecom, & Industrial PWR Supplies; Motor Control and Industrial Systems; Solar Inverters and Optimizers; Appliances such as IOT, Remote Device Monitoring and Home Automation Control.

Several models are available for different current ranges (±5A / ±20A / ±50A) and output (i.e. Ratiometric / Fixed).
