Current sensor Pololu 5322 enables electrically isolated AC and DC current measurement in the range from -50 A to +50 A. The module is based on the Allegro CT432-HSWF50MR TMR sensor IC and provides up to 1 MHz bandwidth with an analog interface. Pololu 5322
Description
Current sensor Pololu 5322 features the Allegro CT432-HSWF50MR IC based on XtremeSense™ TMR (Tunnel Magnetoresistance) technology, enabling bidirectional AC and DC current measurement while maintaining galvanic isolation between the current path and the measurement electronics. The -50 A to +50 A measurement range makes the module suitable for motor drives, inverters, switch-mode power supplies, energy storage systems, and current monitoring applications.
The module operates from a 4.75 V to 5.5 V supply and provides an analog output with a sensitivity of 40 mV/A centered at 2.5 V. A 1 MHz bandwidth, typical response time of 300 ns, and high immunity to high dV/dt events enable operation in fast-switching power electronics. The FLT output indicates when the measured current exceeds approximately 110% of the linear measurement range.
