The CT455-A00B5-SN08 from Allegro MicroSystems is an Automotive-Grade Programmable Contactless Current Sensor designed for consumer, enterprise, and industrial applications. It requires a supply voltage of 5 V and an output current of ±1 mA. This current sensor utilizes Allegro’s patented XtremeSense tunnel magnetoresistance (TMR) technology for precise current measurement in various applications. It offers two standard field ranges (±6 mT and ±48 mT) and a user-programmable variant for customized gain and offset calibration. This AEC-Q100-qualified current sensor has a linear analog output voltage with a 1 MHz bandwidth, ensuring rapid response times of less than 300 ns while maintaining low-noise performance. This RoHS-compliant current sensor is optimized for high dV/dt applications. It is available in a surface-mount package that measures 4.89 x 6 x 1.62 mm and is ideal for solar/power inverters, battery management systems, industrial equipment, power utility meters, DC-DC converters, and power conditioner applications.
