EM1401EVM

Other Parts Discussed in Thread: EM1402EVM

HI Team,

We are using our custom design related to BMS and using EMB1499 and emb1428 ic and MCU itself on same board.

For this we drawn our schematic same as EM1401EVM Development boards.

we are facing issue related to Balancing even in discharge mode only , not any facing issue in charge mode condition. 

Issue: In discharge mode our sec side mosfet are heating more and very less balancing current is flowing i.e. 40mA.

We also know that new Rev of Dev boards (EB1402EVM ) Has isolation between primary winding of transformer and EMB1499 IC but not same as in EB1401EVM .

So, is there any isolation related issue on my boards or something else ?Because we didn't follow the isolation between emb1499 and primary winding of transformer.

i am also attached our schematic.
