Description

Current sensor in the Large Carrier version based on the Allegro ACS72981KLRATR-150U5 chip, designed for unidirectional AC and DC current measurement in the range from 0 A to 150 A. Measurement is performed using Hall-effect sensing in a galvanically isolated current path, enabling current monitoring without a direct electrical connection between the measured circuit and the signal circuitry.

The module operates from a supply voltage of 4.5 V to 5.5 V, with a nominal voltage of 5 V. The analog VIOUT output provides a voltage proportional to the measured current. The sensitivity is 26.7 mV/A at 5 V supply, and the zero-current output voltage is 0.5 V. The low current-path resistance, typically around 0.2 mΩ, minimizes power losses and heat generation when measuring high currents.

A bandwidth of 250 kHz and a response time below 2 µs enable rapid detection of current changes in power supplies, motor drives, DC/DC converters, and energy monitoring systems. The Large Carrier board uses a 6-layer PCB with 2 oz copper to improve heat dissipation under high-current loads. VCC, GND, and VIOUT pins with a 2.54 mm pitch allow easy connection to microcontrollers, breadboards, and measurement circuits.
