This board is a simple carrier of Broadcom's ±30A ACHS-7123 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 mO) current path and electrical isolation up to 3 kV RMS. This version accepts a bidirectional current input with a magnitude up to 30 A and outputs a proportional analog voltage (66 mV/A) centered at 2.5 V with a typical error of ±1.5%.

Product Description

Overview

This current sensor is a carrier board or breakout board for Broadcom's ACHS-7121/7122/7123 Hall effect-based linear current sensors. The following list details some of the sensor's key features:

The conductive path internal resistance is typically 0.7 mO, and the PCB is made with 2-oz copper, so very little power is lost in the board.
Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor's electronics (up to 3 kV RMS), which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
80 kHz bandwidth that can optionally be decreased by adding a capacitor across the board pins marked "filter".
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 zero magnetic hysteresis.
Robust sensor IC can tolerate 100 ms transient current spikes up to 100 A.
Wide operating temperature range of -40°C to 110°C.

The pads are labeled on the bottom silkscreen, as shown in the picture to the right. The silkscreen also shows the direction that is interpreted as positive current flow via the +i arrow.

The ACHS-7123 sensor operates at 5 V and is designed for bidirectional input current from -30 A to 30 A. When Vcc is 5 V, the output voltage is centered at 2.5 V and changes by 66 mV per amp of input current, with positive current increasing the output voltage and negative current decreasing the output voltage. The ACHS-7121 current sensor works as a drop-in replacement for our older Allegro ±30A ACS714 current sensor in many applications.

This board ships assembled with all surface mount components, and a 3×1 strip of 0.1" header pins is included but not soldered in.
