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 5445
Description
ACS37041 Micro Carrier is a compact module based on the Allegro current sensor, using Hall effect technology and providing galvanic isolation for measurements. The device features a very low current path resistance, minimizing energy loss and ensuring high accuracy for both DC and AC current measurements. The analog output offers a wide 150 kHz bandwidth, allowing fast and precise current measurement in dynamic circuits. 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.
The board can be integrated into the current path in various ways, depending on the application. In typical high-current applications, wires up to 10 AWG can be soldered directly to the mounting holes. These holes are also compatible with M3.5 mounting holes and screw terminals with 3.5 mm or 5 mm pitch, facilitating module installation in prototype and final setups. Alternatively, goldpin connectors can be used, although they are not recommended for high currents.
The sensor provides integrated temperature compensation, increasing accuracy across the full operating temperature range of -40°C to 125°C, according to automotive standards. The device is non-ratiometric, meaning its zero point and sensitivity are independent of supply voltage fluctuations, ensuring noise immunity. Its compact size makes it ideal for small projects.
