Product Description
Product Overview
The Allegro CT416 is a high-bandwidth, ultra-low noise integrated contact current sensor utilizing XtremeSense TMR technology. It offers high accuracy current measurements for industrial, consumer, and automotive applications, supporting eight current ranges up to 65 A with a linear analog output voltage. The device features a fast response time of approximately 300 ns, low current consumption, and immunity to common-mode fields. It is designed for applications such as solar/power inverters, UPS, SMPS, telecom power supplies, motor control, power utility meters, and overcurrent fault protection.
