Compact module for bidirectional current measurement using the galvanically isolated Allegro ACS37200LLXTR-100B5 Hall-effect sensor. It provides a ±100 A range, 20 mV/A sensitivity, 150 kHz bandwidth, and a response time below 4 µs. Pololu 5783
Description
Current sensor module Pololu 5783 uses the Allegro ACS37200LLXTR-100B5 Hall-effect sensor with a galvanically isolated current path. It provides bidirectional current measurement from -100 A to +100 A, while the extra-low current path resistance of approximately 0.05 mΩ helps minimize voltage drop and power losses. The analog output offers a 150 kHz bandwidth and a response time below 4 µs.
Sensor operates from a 4.5–5.5 V supply, with 5 V nominal operation, and provides a sensitivity of 20 mV/A. VOUT is centered at approximately 2.5 V at zero current and increases or decreases depending on the current direction. The output is non-ratiometric, so its zero point and sensitivity are largely independent of variations in the supply voltage. A VREF output is also available for improved measurement performance in noisy environments.
Module also provides a FAULT output with a user-configurable overcurrent threshold and an approximately 3 µs response time. The Compact Carrier uses a 2-layer PCB with 2 oz copper, provides a minimum PCB creepage distance of 10.1 mm, and has a 1097 VRMS working isolation rating. The ±100 A value specifies the sensor measurement range; continuous current capability depends on cooling and the quality of the high-current connections.
