Dear Sir,

I have few questions regarding schematicOnboard EV Charger TIDA-00637.

a) Can we replace OPA171 with TLV1805 as it has lesser slew rate.

b) Details of Current Transformer used for Metrology Filtering and for GFCI Test.

c) Details about the data that needed to be stored in EEPROM IC 24C02CSN

Thanks & Regards,

Hello,

pls find my answers below:

a) yes, you can replace it with TLV1805. Actually, in TIDA-010071 we already used TLV1805.

b) for the GFCI test, you can pick up any CT from the shelf, but only need to make sure the max voltage drop on the burn resistor should be in hundreds mV range.

c) With EEPROM you can store some board ID/ rev or any other application related infos.
