Pololu Current Sensor 0A to +65A - 3.3V Logic
The Pololu Current Sensor 0A to +65A - 3.3V Logic is a compact module designed for unidirectional current sensing up to 65A. It uses Allegro’s CT433-HSWF65DR TMR-based sensor, offering high accuracy and electrical isolation with a low primary current path resistance of 1 mΩ. Optimized for high dV/dt applications, this sensor delivers a 1 MHz bandwidth, a fast 300 ns response time, and an analog output proportional to AC or DC currents.
With a 3.3V nominal operation and output sensitivity of 30.8 mV/A, this sensor is suitable for precise current measurement in high-speed switching and electrically isolated systems. It features optional overcurrent fault detection and immunity to noisy power supplies, making it ideal for advanced applications.
