WebBootstrap Drive Circuit Operation The bootstrap circuit is useful in a high−voltage gate driver and operates as follows. When the VS goes below the IC supply voltage VDD or is pulled down to ground (the low −side switch is turned on and the highside switch is turned of f), the bootstrap capacitor, CBOOT, charges through the bootstrap ... WebWith the bootstrap circuit shown in Figure 2, the boot-strap capacitor is always connected to the PH pin. It recharges when PH is at GND potential, which only occurs when the low-side MOSFET is on, and forces the charging of the bootstrap capacitor to be coincident with the switching of the power MOSFETs. This is not the case with

A bootstrap circuit is one where part of the output of an amplifier stage is applied to the input, so as to alter the input impedance of the amplifier. When applied deliberately, the intention is usually to increase rather than decrease the impedance.
