hello,
My question concernsthe control of thedischargeFETwhen the conditionsOC1STTIERDSGoccures.On my boardwhenthe discharge currentexceeds thethresholdOC1tierdsg, we observe something like acapacitor discharge which will increaseof about one second the opening of thedischargeFET.while on thedemoboardI do not havethe same thing.
How does thedrive of controlFETs work on theBQ20Z95? is there an internal power DC/DC burst ?
would you havean idea of myproblem?
