ACS37041 Current Sensor Compact Carriers

ACS37041 Current Sensor Compact Carrier pinout.

We are offering these breakout boards with support from Allegro Microsystems as an easy way to use or evaluate their ACS37041 Hall effect-based, electrically isolated current sensors; we therefore recommend careful reading of the ACS37041 datasheet before using this product. The following list details some of the sensor’s key features:

• Hall effect-based sensor with electrically isolated current path allows the sensor to be inserted anywhere along the current path and to be used in applications that require galvanic isolation.
• Low primary current path resistance of 1.6 mΩ in the sensor IC, so very little power is lost in the module.
• 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.
• High-bandwidth 150 kHz analog output voltage proportional to AC or DC currents.
• Less than 5 µs response time.
• 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 temperature compensation circuitry allows improved accuracy over the full operating temperature range.
• Automotive-grade operating temperature range of -40°C to 125°C.
• Carrier boards, available in micro (0.3″×0.4″) and our standard compact (0.7″×0.8″) sizes, offer a variety of ways to insert it into the current path along with 0.1″-pitch (breadboard-compatible) power, ground, and output pins.
• 3.3V and 5V versions available.

These sensors are the larger versions with our standard compact form factor, which matches the compact form factor available for many of our other current sensor carriers. Micro versions with smaller 0.3″×0.4″ PCBs are available for integration into more space-constrained applications or for evaluation of the IC’s performance with a smaller PCB area for thermal dissipation.
