Compact current measurement module using the Allegro ACS37100LMATR-050B3 TMR sensor with a galvanically isolated current path. It enables bidirectional current measurement in the ±50 A range, offering measurement bandwidth up to 10 MHz and a short response time of approximately 50 ns. Pololu 5477
Description
Module Pololu was designed as a convenient carrier board for the Allegro ACS37100LMATR-050B3 current sensor. The sensor uses TMR technology and provides galvanic isolation of the current measurement path. The measurement range is -50 A to +50 A, while the typical sensitivity is 26.4 mV/A. With a 3.3 V supply voltage, the output voltage at 0 A is approximately 1.65 V.
High measurement bandwidth up to 10 MHz and a typical response time of approximately 50 ns allow the module to be used in fast control systems, power converters, motor drives, and energy monitoring systems. The low resistance of the main current path, typically 1.2 mΩ, helps reduce voltage drop and power losses. The analog VOUT output is proportional to the measured current, while the additional VREF output can be used to reduce errors caused by reference voltage shifts and noise.
The carrier uses a 2-layer PCB with 2 oz copper and includes a routed slot to increase creepage distance. The minimum PCB creepage distance is approximately 9.3 mm, while the sensor IC isolation rating is 1097 VRMS. The compact board measures approximately 20.3 × 27.9 mm and weighs approximately 2.1 g.
