CT427 XtremeSense® TMR Sensors

Allegro MicroSystems CT427 XtremeSense® TMR Sensors offer a 0.30µs response time, ≤±1.0% FS total error output, and 3V to 3.6V supply voltage range. These sensors feature XtremeSense TMR technology that enables high accuracy current measurements for various applications. CT427 sensors support two current ranges where the integrated current-carrying conductor (CCC) handles up to 30A of current and generates a current measurement as a linear analog output voltage. Allegro MicroSystems CT427 XtremeSense TMR Sensors are ideal for white goods, battery management systems, consumer electronics, and telecom power supplies.
