Allegro MicroSystems CT455 XtremeSense™ TMR Contactless Current Sensors

Allegro MicroSystems CT455 XtremeSense™ TMR Contactless Current Sensors are high-bandwidth and low-noise sensors that enable high-accuracy current measurements for consumer, enterprise, and industrial applications. After calibration, these current sensors achieve a total error output of less than ±1% over supply voltage and temperature. The CT455 contactless current sensors are also offered in a user-programmable variant, which allows end-of-line calibration of offset and gain. These current sensors are compact, feature a simple design, and are equipped with a filter function to reduce the noise on the output pin.

The CT455 contactless current sensors feature more than -50dB effective common-mode rejection, 1MHz bandwidth, <300ns response time, and a 3.3V or 5V supply voltage range. These current sensors are assembled in an 8-lead SOIC package and a low-profile, industry-standard 8-lead TSSOP package that is green and RoHS-compliant. Typical applications include solar/power inverters, battery management systems, industrial equipment, power utility meters, power conditioners, and DC/DC converters.
