Allegro CT415 HSN820MR ultra low noise current sensor ideal for battery management and motor control
Product Overview
The Allegro CT415 is a high-bandwidth, ultra-low noise integrated contact current sensor utilizing Allegro's XtremeSense TMR technology. It offers high accuracy current measurements with a total output error of approximately 1.0% full-scale across various industrial, consumer, and automotive applications. The device supports eight current ranges up to 65 A, featuring an integrated current-carrying conductor (CCC) and providing a linear analog output voltage. With a fast response time of approximately 300 ns and immunity to common-mode fields, it is suitable for applications like solar/power inverters, UPS, SMPS, battery management systems, and motor control.
