The CT455-A00B3-TS08 from Allegro MicroSystems is an Automotive-Qualified Programmable Contactless Current Sensor that is designed to perform high-accuracy current measurements for consumer, enterprise, and industrial applications. It requires a supply voltage of 3.3 V and an input current of 6 mA. This AEC-Q100-qualified current sensor utilizes Allegro’s patented XtremeSense tunnel magnetoresistance (TMR) technology. It is designed to sense and translate the magnetic field into a linear analog output voltage. This user-programmable current sensor enables end-of-line calibration of gain and offset. It has less than 300 ns output response time and is optimized for high dV/dt applications. This RoHS-compliant current sensor is available in a surface-mount package that measures 3 x 6.4 x 1.1 mm and is ideal for solar/power inverters, battery management systems, industrial equipment, power utility meters, DC-DC converters, and power conditioner applications.
