Product Description

This board is a simple carrier of Allegro’s ACS71240KEXBLT-050U5 Hall effect-based, electrically isolated current sensor, which offers a low-resistance (~0.6 m?) current path and a high 120 kHz bandwidth for fast response times.

Part Suffix: 050U5
Range: 0-50 A (unidirectional)
Supply Voltage: 4.5 V to 5.5 V
Sensitivity: 80 mV/A
Zero Point: 0.5 V
Fault Trip Level: 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.

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 electrical isolation.
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.
High-bandwidth 120 kHz analog output voltage proportional to AC or DC currents.
Overcurrent fault output with 1.5 µs response time indicates when the current exceeds the optimized sensing 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.
0.7?×0.8? carrier board offers a variety of ways to insert it into the current path and 0.1?-pitch (breadboard compatible) power, ground, and output pins.

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.

This carrier features the ACS71240KEXBLT-050U5, which is intended for operation around 5 V and is designed for unidirectional input current from 0 A to 50 A. This version can be visually distinguished from the other versions by the “5V U50” printed on the bottom side.
