The ACS37035 Series from Allegro MicroSystems are Hall-Effect Current Sensors. These current transducers require a supply voltage of 3.3 V or 5 V and offer current sensing of up to 65 A. They have a quiescent output voltage of 1.65 or 2.5 V and a sensitivity of up to 100 mV/A. This current sensor has a high operating bandwidth of 1 MHz for fast control loops or where high-speed currents are monitored and a response time of 0.45 us. They provide high isolation by magnetically coupling the field generated by the current in the conductor to the monolithic. These UL 62368-1 certified current transducers offer user-configurable overcurrent FAULT detection, allowing short-circuit detection for system protection with a fault threshold that is proportional to the current range.
These transducers utilize Allegro's Hall-effect-based current sensing technology to achieve reinforced isolation of up to 1000 VRMS. These AEC-Q100 automotive-grade sensors have a low internal primary conductor resistance of 1 milli-ohm for better power efficiency. These RoHS-compliant current transducers are available in surface-mount packages that measure 10.21 x 10.31 x 2.54 mm and are suitable for load detection and management, switch-mode power supplies, and motor control applications.
