The Pololu ACS72981KLRATR-150B5 Current Sensor Compact Carrier -150A to +150A, 5V is a compact current sensor utilizing Allegro’s Hall effect technology. It provides an electrically isolated current path with a low resistance of approximately 0.2 mΩ and a high bandwidth of 250 kHz for rapid response. Designed for nominal 5 V operation, it accommodates bidirectional currents ranging from -150 A to +150 A. The sensor features differential Hall sensing to minimize interference from common-mode fields and includes digital temperature compensation for enhanced accuracy across varying temperatures. The carrier board aids in heat dissipation, allowing continuous conduction of 60 A without exceeding thermal limits. Note: The sensor is intended for use below 30 V, and exceeding temperature or current limits may result in permanent damage.
