Too high and some FETs will start to turn on (only ones wity very low Vth).Īs they note - only wity Al caps do you ned to worry about leakage. This should be in the data sheet but Id ot expect it to be 1V and maybe much less. Unfortunately, by looking at the suggested schematic (see below) Im unable to understand what value should I be using for this.ĭoes the capacitor need to be bigger than this in practice If so, is there a rule of thumb saying how big Is there a drawback to having a large bootstrap capacitor.

The load cannot be connected between high and low side MOSFETs 3. ![]() The load cannot be connected between high and low side MOSFETs 3.Ī H-bridge circuit needs a pair of IR2110. To chargedischarge the bootstrap capacitor(C2 in your schematic) the high and low sides cannot turn on simutanously but by turn.
