Description Pololu CT433-HSWF20DR TMR Current Sensor Compact Carrier 0A to 20A, 3.3V Features 1 MHz high-bandwidth output Offers 300 ns typical response time Utilizes Allegro's XtremeSense™ TMR tech Provides non-ratiometric output stability Includes optional overcurrent fault output The Pololu CT433-HSWF20DR TMR Current Sensor Compact Carrier 0A to 20A, 3.3V is a compact, electrically isolated current sensor optimized for high dV/dt applications. It utilizes Allegro’s XtremeSense™ TMR technology to provide high accuracy and bandwidth for AC or DC current measurements. The sensor offers a 1 MHz analog output voltage and a typical response time of 300 ns. It is designed for unidirectional input currents from 0 A to 20 A and operates within a temperature range of -40°C to 125°C. The sensor's output is non-ratiometric, ensuring stability against supply voltage variations. It features an optional overcurrent fault output that activates when the current exceeds 110% of the maximum s
