Description

Current sensor module Pololu 5782 uses the Allegro ACS37200LLXTR-200B3 Hall-effect sensor with a galvanically isolated current path. The device provides bidirectional current measurement from -200 A to +200 A. Its analog measurement output offers a bandwidth of 150 kHz, while the sensor response time is 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. The VOUT analog output is centered at approximately 1.65 V at zero current and changes proportionally to 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.

Current path resistance is approximately 0.05 mΩ, helping to reduce voltage drop and power losses. The compact carrier uses a 2-layer PCB with 2 oz copper, provides a 1097 VRMS working isolation rating, and a minimum PCB creepage distance of 10.1 mm. The ±200 A rating specifies the measurement range; actual continuous current capability depends on cooling and operating conditions.
