<p class="MsoNormal" style="margin-bottom:12.0pt">Podle mě to "charging" a "discharging" je myšleno naopak.<br>
Tedy pokud je napětí v mezích, tak jsou oba tranzistory otevřené.<br>
Pokud hrozí přebití, tak ten "charging" se zavře. A jeho substrátová dioda je orientovaná tak, že ani přes ni nic neprojde.<br>
A podobně ten druhý v případě podpětí.<br>

do série a navíc jeden se zove „charging“ a druhý „discharging“? Ten ochranný obvod si je obejde protože má baterii připojenou napřímo ale ten nabíjecí je vždy bude mít v cestě… Viz výřez ze schématu obvodu 8254A.</span><o:p></o:p></p>
