The Pololu ACS37220LEZATR-100B5 Current Sensor Large Carrier -100A to +100A, 5V is a Hall effect-based sensor designed for nominal 5V operation, capable of measuring bidirectional currents from -100A to +100A. It features an electrically isolated current path with an extra-low resistance of approximately 0.1 mΩ, ensuring high efficiency. The sensor provides a high bandwidth of 150 kHz for rapid response and includes a user-configurable overcurrent fault output for fast short-circuit detection. Integrated digital temperature compensation enhances accuracy across a wide automotive-grade temperature range. Note: This product is intended for use below 30V and can get hot enough to cause burns; handle with care.
