Product Description

This board is a simple compact carrier of Allegro’s ACS72981LLRATR-050B3 Hall effect-based linear current sensor, which offers a low-resistance (~0.2 m?) current path and a high 250 kHz bandwidth for fast response times.

This carrier features the ACS72981LLRATR-050B3, which is intended for nominal 3.3 V operation and is designed for bidirectional input current from -50 A to +50 A.

We are offering these breakout boards with support from Allegro Microsystems as an easy way to use or evaluate their ACS71240 Hall effect-based linear current sensors; we therefore recommend careful reading of the ACS71240 datasheet before using this product. The following list details some of the sensor’s key features:

Differential Hall sensing rejects common-mode fields, so the orientation of the sensor relative to uniform external magnetic fields (e.g. the Earth’s magnetic field) has less effect on the measurement.
The conductive path internal resistance is typically 0.6 m?, and the PCB is made with 2-oz copper, so very little power is lost in the module.
Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor’s electronics, which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
High 120 kHz bandwidth for fast response times.
Overcurrent fault output with 1.5 µs response time indicates when the current exceeds the optimized operating range.
Output is not ratiometric (i.e. the zero point and sensitivity are independent of the actual supply voltage), which provides immunity from noisy supplies.
Integrated digital temperature compensation circuitry allows for near closed loop accuracy over temperature in an open loop sensor.
Automotive-grade operating temperature range of -40°C to 125°C.

The pads are labeled on the bottom silkscreen. The silkscreen also shows the direction that is interpreted as positive current flow via the +i arrow.
