Description
Current sensor module Pololu 5792 uses the Allegro ACS37200LLXTR-200B3 Hall-effect sensor with a galvanically isolated current path. It provides bidirectional current measurement from -200 A to +200 A, while the extra-low current path resistance of approximately 0.05 mΩ helps minimize voltage drop and power losses. The analog output provides a 150 kHz bandwidth and a response time below 4 µs.
Sensor operates from a 3.15–3.45 V supply, with 3.3 V nominal operation, and provides a sensitivity of 6.6 mV/A. VOUT is centered at approximately 1.65 V at zero current and changes proportionally to the magnitude and direction of the measured current. The module also provides a VREF output and a FAULT output with a user-configurable overcurrent threshold and an approximately 3 µs response time.
Large Carrier version uses a 6-layer PCB with 2 oz copper and provides several options for high-current connections, including holes for M6 or 1/4″ hardware and direct soldering of wires up to 4 AWG. The minimum PCB creepage distance is 10.4 mm, while the sensor IC has a 1097 VRMS working isolation rating. The board measures approximately 35.6 × 30.5 mm.
