Allegro announces XtremeSense TMR current sensors
Allegro MicroSystems has launched its latest XtremeSense TMR current sensors - CT4022 and CT4032 - for clean energy applications requiring optimal noise performance and high-precision current measurements.
“Allegro's new XtremeSense TMR current sensors set an industry standard for low-noise magnetic current sensing,” said Matt Hein, business line director of current sensors at Allegro.
“They achieve a 2x reduction in root mean square (RMS) noise versus previous TMR solutions and a 4x reduction compared to Hall-based integrated conductor solutions. The result is highly efficient power conversion, even at light load operation, enabling superior performance in heat pumps and solar inverters to the latest generation of EV chargers.”
The CT4022/32 expand Allegro's high-precision XtremeSense TMR current sensing portfolio by measuring current flowing through an integrated conductor and rejecting interference from external stray magnetic fields. The sensors are tailored for clean energy systems, where maximising power conversion efficiency is critical. Integrated galvanic isolation enables low-side, high-side or in-line current sensing in applications up to 1000V.
The CT4022 is available in an industry-standard 8-pin SOIC, and the CT4032 is available in an industry-standard 16-pin widebody SOIC.
