As an application example of an improved bootstrap configuration with switchable bootstrap loop, a driver is proposed in which the bootstrap capacitor is not charged from the input but by the power supply voltage VH. When this driver is switched off, the bootstrap capacitor is discharged only to VH, thus considerably reducing the power dissipation and relieving the input driver.
