CT4022 & CT4032 XtremeSense TMR Current Sensors

Allegro MicroSystems CT4022 and CT4032 XtremeSense TMR Current Sensors deliver superior noise performance and high-precision current measurements for high-voltage, power-dense clean energy applications. These Allegro current sensors measure current flowing through an integrated conductor and reject interference from external stray magnetic fields. The sensors are tailored for clean energy systems, where maximizing 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 comes in an 8-pin SOIC package, and the CT4032 comes in an industry-standard 16-pin wide-body SOIC package.
