Other Parts Discussed in Thread: LM7321
We are working on 240V EV for US standard. This design need to implement J1172 compliant. We have refer to TIDA-00637 design, and have some question about metering and GFCI design.
- Can the GFCI section of the line detect the 4-6mA leakage current? Whether the smooth DC current can be detected ?
- What is the response time when the GFCI fault is triggered?
- The LM7321 is used to the GFCI detection. May I know it has any spec need on this design? Do we have other alterative solution to suggestion.
- Could you share the spec of GFCI CT configuration(Figure 15)? Or you have guideline to design this CT.
