A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features a high-sensitivity analog VOUT output with a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and its low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5450
ACS37042 Micro Carrier is a compact module based on the Allegro current sensor, utilizing Hall effect technology and providing galvanic isolation for measurement. The device features a very low current path resistance of ~1.6 mΩ, minimizing energy losses and ensuring high accuracy for both DC and AC current measurements. The analog output offers a wide 150 kHz bandwidth, enabling fast and precise current measurement in dynamic systems. The sensor response time is less than 5 µs, making it ideal for applications requiring rapid response.
The module has five essential pins: current inputs IP+ and IP-, logic supply VDD and GND, and signal output VOUT. Power should be connected to the VDD and GND pads marked on the bottom of the board. The VOUT output generates an analog signal with a resting voltage of 1.65 V, which changes proportionally to the input current. Positive current increases the output voltage, while negative current decreases it, with a sensitivity of 132 mV/A.
The board can be integrated into the current path in various ways depending on the application. In typical high-current applications, wires can be soldered directly to the mounting holes. These holes are also compatible with screw terminals with a 3.5 mm or 5 mm pitch, making it easy to install the module in both prototype and final setups. Alternatively, goldpin connectors can be used.
The sensor provides integrated temperature compensation, improving accuracy across the full operating temperature range of -40°C to 125°C, in compliance with automotive standards. The device is non-ratiometric, meaning its zero point and sensitivity are independent of supply voltage fluctuations, ensuring noise immunity. The module is designed to operate at 3.0 V to 3.6 V and supports a bidirectional measurement range of -10 A to +10 A. Thanks to its compact size, it is ideal for small-scale projects.
