TIDA-010237: fault current thresholds of 6 mA DC, 30 mARMS(IEC62955)

Part Number: TIDA-010237
Other Parts Discussed in Thread: AMC131M03

Recently, AC EV charger companies are developing solutions to cope with IEC62955(sense fault current thresholds of 6 mA DC, 30 mA AC based off) .

There are companies that implement using AMC131M03 and companies that implement using TIDA-010237 solutions.

Which solution is more advantageous for IEC62955?

Thanks

Hello,

I am not familiar with the AMC131M03 implementation of RCD. I am looking into this and will get back to you within 2 days.

Hello,

Apologies for the late reply. The TIDA-010237 is better from a number of components perspective. The 237 design integrates some of the analog components on the M0 reducing the number of necessary components.
