Current measurement module using the galvanically isolated Allegro ACS37030LMYATR-040B3 sensor. A combination of Hall-effect sensing and an inductive coil provides DC to 5 MHz measurement bandwidth, a ±40 A range, and a typical response time of 40 ns. The larger carrier board facilitates high-current connections. Pololu 5698
Description
Current sensor module Pololu 5698 uses the Allegro ACS37030LMYATR-040B3 electrically isolated current sensor. The device provides bidirectional current measurement from -40 A to +40 A and uses two signal paths: a Hall-effect sensor for DC and low-frequency current information and an inductive coil for high-frequency signals. This combination provides measurement bandwidth from DC to 5 MHz and a typical response time of approximately 40 ns.
Sensor operates from a 3.0–3.6 V supply, with 3.3 V nominal operation, and provides a sensitivity of 33 mV/A. The analog VOUT output is centered at 1.65 V at zero current and changes proportionally to the measured current. The VREF output provides a zero-current reference for noise-sensitive applications, while the non-ratiometric output characteristic reduces the influence of supply voltage variations on sensitivity and zero point.
Large Carrier version uses a 6-layer PCB with 2 oz copper, providing improved heat dissipation and more space for high-current connections. The galvanically isolated current path provides a working isolation rating of 1000 VRMS, while the minimum PCB creepage distance is approximately 11.9 mm. The current path resistance is typically 0.9 mΩ, and the board measures approximately 35.6 × 30.5 mm.
