ACS709 Current Sensor (from -75 A to + 75 A)

0104110000010278

New product

This board is a simple carrier of Allegro’s ±75A ACS709 Hall effect-based linear current sensor with overcurrent fault output, which offers a low-resistance (~1.1 mΩ) current path and electrical isolation up to 2.1 kV RMS. The sensor has optimized accuracy for currents from -37.5 A to 37.5 A, and the analog voltage output is linear for current magnitudes up to 75 A.

More info

The following list details some of the sensor’s key features:

  • Optimized accuracy for bidirectional input current from -37.5 A to 37.5 A, with a linear sensing range from -75 A to 75 A (see warning note below for thermal limitations).
  • Conductive path internal resistance is typically 1.1 mΩ, and the PCB is made with 2-oz copper, so very little power is lost in the board.
  • Integrated shield greatly reduces capacitive coupling from current conductor to die and prevents offset drift in high-side applications.
  • Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor’s electronics (up to 2.1 kV RMS), which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
  • 120 kHz bandwidth that can optionally be decreased by adding a capacitor across the board pins marked “FILT”.
  • High accuracy and reliability: typical total output error of 2% at room temperature with factory calibration, an extremely stable quiescent output voltage
  • Automotive-grade operating temperature range of -40°C to 150°C.
  • User-settable overcurrent threshold: FAULT pin output latches low when current exceeds the configured threshold for a duration that can be set through the addition of an external capacitor.
