Description Pololu CT432-HSWF50MR TMR Current Sensor Compact Carrier -50A to +50A, 5V Optimizes high dV/dt applications Ensures precise -50A to +50A current measurement Features non-ratiometric output for stability Minimizes power loss with 1 mΩ resistance Responds quickly with 300 ns typical time The Pololu CT432-HSWF50MR TMR Current Sensor Compact Carrier -50A to +50A, 5V is a compact, electrically isolated current sensor optimized for high dV/dt applications. It utilizes Allegro’s XtremeSense™ TMR technology for precise current measurements with a high 1 MHz bandwidth and low noise. The sensor is designed for bidirectional input currents ranging from -50A to +50A and operates at a nominal 5V. It features a non-ratiometric output, ensuring stability against supply voltage variations, and offers an optional overcurrent fault output. The sensor's design minimizes power loss with a 1 mΩ primary current path resistance and a 4-layer PCB construction. It provides an analog output
