Pololu ACS72981LLRATR-050B3 Current Sensor Compact Carrier -50A to +50A, 3.3V

Description Pololu ACS72981LLRATR-050B3 Current Sensor Compact Carrier -50A to +50A, 3.3V Measures bidirectional currents from -50A to +50A Ensures fast response with high-bandwidth 250 kHz Integrates digital temperature compensation Outputs ratiometric analog voltage on VIOUT Compact dimensions: 0.7″×0.8″ The Pololu ACS72981LLRATR-050B3 Current Sensor Compact Carrier -50A to +50A, 3.3V is a Hall effect-based, electrically isolated current sensor designed for nominal 3 V operation. It measures bidirectional input currents ranging from -50 A to +50 A with a low-resistance current path and a high bandwidth of 250 kHz, ensuring fast response times. The sensor outputs a ratiometric analog voltage centered at VCC/2, which varies with the input current. Integrated digital temperature compensation enhances accuracy across the operating temperature range. Note: This product is intended for use below 30 V and can become hot during operation.
