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 5452

Description

ACS37042 Micro Carrier is a compact module based on an Allegro current sensor that uses Hall-effect technology and provides galvanic isolation of the measurement. The device features very low current path resistance of ~1.6 mΩ, which minimizes energy loss and ensures high accuracy for both DC and AC current measurement. The analog output provides a wide bandwidth of 150 kHz, 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 feedback.

The module includes five essential pins: current inputs IP+ and IP-, logic supply VDD and GND, and signal output VOUT. Supply voltage should be connected to the VDD and GND pads marked on the underside of the board. The VOUT output generates an analog signal with a resting value of 2.5 V, which shifts proportionally to the input current. Increasing current in the positive direction raises the output voltage, while negative current decreases it, with a sensitivity of 200 mV/A.

The board can be integrated into the current path in different ways, depending on the application. In typical high-current applications, it is possible to solder wires directly to the mounting holes. These holes are also compatible with screw terminals with 3.5 mm or 5 mm pitch, making it easier to use the module in both prototype and final installations. Alternatively, goldpin headers can be used.

The sensor provides integrated temperature compensation, improving accuracy across the full operating temperature range from -40°C to 125°C, in compliance with automotive standards. The circuit is non-ratiometric, meaning its zero point and sensitivity are independent of supply voltage fluctuations, ensuring noise immunity. The module operates at a supply voltage from 4.5 V to 5.5 V and supports a bidirectional measurement range from -10 A to +10 A. Thanks to its small size, it is perfectly suited for use in compact projects.
