Description

  • Pololu ACS37220LEZATR-100B5 Current Sensor Compact Carrier -100A to +100A, 5V
  • Measures currents -100A to +100A
  • Ensures high efficiency with 0.1mΩ resistance
  • Features 150 kHz bandwidth for rapid response
  • Includes user-configurable overcurrent detection
  • Enhances accuracy with digital temperature compensation

The Pololu ACS37220LEZATR-100B5 Current Sensor Compact Carrier -100A to +100A, 5V is a compact carrier for Allegro’s Hall effect-based current sensor, designed for nominal 5 V operation. 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.

This sensor is capable of measuring bidirectional currents from -100 A to +100 A, with an analog output voltage that is proportional to the input current. Integrated digital temperature compensation enhances accuracy across a wide operating temperature range from -40°C to 150°C.

Note: This product is intended for use below 30 V. Exceeding temperature or current limits can cause permanent damage to the sensor. Handle with care to avoid burns.
