Current sensor Allegro CT415-HSN865MR with 300 nanosecond response time and low current consumption
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 (FS) across various industrial, consumer, and automotive applications. The device supports eight current ranges, with an integrated current carrying conductor (CCC) capable of handling up to 65 A and providing a linear analog output voltage. It features a fast 300 ns output response time, low current consumption (~6.0 mA), and immunity to common-mode fields. The CT415 includes a filter function to reduce output noise and is available in an industry-standard, green, RoHS-compliant 8-lead SOIC package. This device is classified as NOT FOR NEW DESIGN and is restricted to existing customer applications.
