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 the low current path resistance minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5444

Description

ACS37041 Micro Carrier is a compact module based on the Allegro current sensor, which utilizes Hall effect technology and provides galvanic isolation for current measurement. The device features a very low primary path resistance, minimizing energy losses and ensuring high accuracy for both DC and AC current measurements. The analog output offers a wide bandwidth of 150 kHz, allowing for fast and precise current measurement in dynamic circuits. The sensor’s response time is less than 5 µs, making it ideal for applications that require rapid response.

The module includes five essential pins: current inputs IP+ and IP-, logic power supply VDD and GND, and the signal output VOUT. The supply voltage should be connected to the VDD and GND pads located on the bottom of the board. The VOUT pin outputs an analog signal with a resting value of 1.65 V, which changes proportionally to the input current. An increase in current in the positive direction raises the output voltage, while negative current causes it to drop.

The board can be integrated into the current path in several ways, depending on the application. In typical high-current setups, it is possible to solder 10 AWG wires directly to the mounting holes. These holes are also compatible with M3.5 mm screws as well as screw terminals with a 3.5 mm or 5 mm pitch, making it easy to install the module in both prototype and final systems. Alternatively, goldpin connectors can be used, although they are not recommended for high-current applications.

The sensor features integrated temperature compensation, improving accuracy across the full operating temperature range from -40°C to 125°C, compliant with automotive standards. The circuit is non-ratiometric, meaning its zero point and sensitivity are independent of power supply fluctuations, ensuring strong noise immunity. Thanks to its compact size, the module is ideal for use in small electronic projects.
