Description Pololu CT432-HSWF70DR TMR Current Sensor Large Carrier 0A to 70A, 5V Offers 1 MHz bandwidth for high dV/dt applications Ensures high accuracy with XtremeSense™ TMR technology Minimizes power loss with 1 mΩ primary resistance Features non-ratiometric, stable output in noise Includes optional overcurrent fault output The Pololu CT432-HSWF70DR TMR Current Sensor Large Carrier 0A to 70A, 5V is a sophisticated current sensor designed for high dV/dt applications, offering a 1 MHz bandwidth with low noise. Utilizing Allegro’s XtremeSense™ TMR technology, it provides high accuracy and electrically isolated current measurements. The sensor is optimized for unidirectional input currents from 0 A to 70 A and operates at a nominal 5 V. It features a non-ratiometric output, ensuring stability against noisy supplies, and includes an optional overcurrent fault output. The sensor's design minimizes power loss with a 1 mΩ primary current path resistance and a 6-layer PCB construction. It is suitable for applications requiring electrical isolation and can be integrated into various current paths. The sensor's output is an analog voltage proportional to AC or DC currents, with a typical response time of 300 ns. 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.
