I'm building up some prototype boards using the BQ24630. I have 1 set of board working perfectly using similiar components recommended on the datasheet, but the other 4 boards don't seem to work at all. All signals measured are within spec., except the REGN pin. The good one has REGN of about 6V, but the bad ones have only about 0.5V. Any reasons why REGN is low? Thanks.
