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 Web28 de nov. de 2024 · \$\begingroup\$ UVLO has absolutely nothing to do with the bootstrap voltage, it detects the VCC voltage to prevent driving under conditions where the low side is not driven completely. This is because the failure to provide a low on the external FETs will result in no charge on the bootstrap caps. The circuit would still try to work, but the …

"WebAlthough the bootstrap method has many advantages, it imposes significant limitations because of inherent charge time requirements. The capacitor can supply current to keep the high-sideMOSFET on for multiple switching cycles; however, once the charge is depleted, the circuit is forced to switch for a brief period of time to recharge the capacitor.
