ACHS-7124 Current Sensor Carrier -40A to +40A

CHF5.52

This board is a simple carrier of Broadcom’s bidirectional ±40A ACHS-7124 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 mΩ) current path and electrical isolation up to 3 kV RMS. This version accepts a bidirectional current input with a magnitude up to 40 A and outputs a proportional analog voltage (50 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.

This current sensor is a carrier board or breakout board for Broadcom’s ACHS-7121/7122/7123/7124/7125 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 mΩ, 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.
