The Pololu ACS37220LEZATR-150B3 Current Sensor Compact Carrier -150A to +150A, 3.3V is a compact carrier for Allegro's Hall effect-based, electrically isolated current sensor. It features an extra-low-resistance current path and a high bandwidth of 150 kHz for rapid response times. The sensor is designed for bidirectional input current ranging from -150 A to +150 A and operates nominally at 3 V. It includes a user-configurable overcurrent fault output for fast short-circuit detection and integrated digital temperature compensation for improved accuracy across a wide temperature range. Note: This product is intended for use below 30 V and can get hot enough to cause burns; handle with care.
