AMC3301: Current sense with similar spec. and with over current protection

Freddy Hsieh

Part Number: AMC3301

Tool/software:

AMC3301 is used for AC-current sensing of  a EV fast-charging station. I am looking for TI solution with similar spec. as AMC3301 but also with over current protection. Thank you.

    Hi Freddy,

    The output of the AMC3301 can be used to detect over-current if the input is sized to detect different thresholds. However, this is subject to the 3uS latency of the main signal path. 

    If a faster over-current detection is necessary they could consider using an isolated comparator in parallel, sensing across the same resistor. 

    Please see this application note for additional details: https://www.ti.com/lit/ab/sbaa605/sbaa605.pdf

    It is best to run the AMC33xx device from a 5V supply on the low side in this configuration.
