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 Allegros 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 -40C to 125C.
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 sensing range. The compact carrier board facilitates easy integration into various applications requiring electrical isolation.
Note: This product is intended for use below 30 V. Exceeding temperature or current limits can cause permanent damage to the sensor.
