Products with components from Allegro Microsystems

These carrier boards for Allegro’s A4988 bipolar stepper motor driver feature adjustable current limiting, over-current and over-temperature protection, and five microstep resolutions (down to 1/16-step). They operate from 8 V to 35 V and can deliver approximately 1 A per phase without a heat sink (they are rated for up to 2 A per coil).

These carrier boards for Allegro’s A5984 stepper motor drivers are great low-cost solutions for controlling bipolar stepper motors. They operate from 8 V to 40 V and can deliver up to 1.2 A continuous per phase (2 A peak). Fixed and adjustable current limit versions are available.

Monitor voltage, current, power, and other parameters in AC and DC systems with these boards featuring Allegro’s ACS37800KMACTR-030B3-I2C isolated power monitoring IC. They provide bidirectional current measurements from -30 A to +30 A and can be configured to measure voltages up to 480 V_RMS nominal (±980 V peak).

These boards are simple carriers of Allegro’s contactless current sensors, which measure the magnetic field of the current flowing through a nearby conductor without needing to be connected in series with the circuit. They output an analog voltage proportional to the magnetic field that with simple calibration can be converted into an accurate current measurement.

These boards are simple carriers of Allegro’s high-dV/dt, high bandwidth (1 MHz) CT432/CT433 tunneling magneto­resistance (TMR) current sensors, which output an analog voltage proportional to the current passing through them. They offer common-field mode rejection, a low-resistance (~1 mΩ) current path, and overcurrent fault. 3.3V and 5V versions are available.

These boards are simple carriers of Allegro’s high-current ACS37220 Hall effect-based, galvanically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing, an extra-low-resistance (~0.1 mΩ) current path, and configurable overcurrent fault. 3.3V and 5V versions are available.

These boards are simple carriers for Allegro’s ACS37041/2 Hall effect-based, galvanically isolated current sensor in a 5-pin SOT-23 package with ~1.6 mΩ current path resistance, differential sensing, and 150 kHz bandwidth. 3.3V and 5V versions are available with up to ±30A current range.

These boards are simple carriers of Allegro’s 3.3V ACS37030 DC to 5 MHz bandwidth, galvanically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing for higher accuracy, a low-resistance (~0.7 mΩ) current path, and a zero-current reference output.

These boards are simple carriers of Allegro’s ACS71240 Hall effect-based, galvanically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing for higher accuracy and a low-resistance (~0.6 mΩ) current path. 3.3V and 5V versions are available.

These boards are simple carriers of Allegro’s high-current ACS72981 Hall effect-based, galvanically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing, a low-resistance (~0.2 mΩ) current path, and a high 250 kHz bandwidth. 3.3V and 5V versions are available.

These boards are simple carriers of Allegro’s 5V ACS724 Hall effect-based, galvanically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing for higher accuracy and a low-resistance (~0.6 mΩ) current path.

These boards are simple carriers of Allegro’s ACS711 Hall effect-based, galvanically isolated current sensors, which work with both 3.3V and 5V supplies and output an analog voltage proportional to the current passing through them.
