Description
This current sensor is a carrier board or breakout board for the Allegro ACS714LLCTR-05B-T Hall effect-based linear current sensor. The sensor operates at 5V with an output sensitivity of 185 mV / A. The board is fully populated with SMD components, including the ACS714. These components can also be seen in the picture.
We recommend carefully reading the ACS714 datasheet, as you need to be familiar with the sensor before putting it into operation, to avoid the risk of destroying it.
Features:
-
Designed for bidirectional input current of -5 to 5 A (however, the rugged sensor IC survives up to five times more current).
-
The typical path internal resistance is usually 1.2mOhm. The PCB is made of 2 oz copper, so very little power is lost on the board.
-
By using the Hall effect, the IC is able to electrically isolate the path from the sensor electronics. This allows the sensor to be used in projects where electrical isolation is important. The sensor can also be placed at any point in the path.
-
80 kHz bandwidth, which can be reduced if necessary by adding a capacitor on the pin row.
-
High accuracy and reliability: typical total output error of ± 1.5% at room temperature with factory calibration, an extremely stable output offset voltage, and almost no magnetic hysteresis.
-
Automotive-grade operating temperature range from -40 ° C to 150 ° C
The pads are labeled in silkscreen on the underside, as shown in the image on the right. The silkscreen also shows the direction that is interpreted as positive current flow via the +i arrow.
Like almost all of our carrier boards, this sensor is assembled with all of its required surface-mount components, as shown in the main product image.
This version is marked with a blue X. We also sell a 30A version and a unidirectional ± 30A bidirectional version of this board. You can tell these versions apart by reading the text on the IC or by looking at the color of the X in the underside silkscreen.
