Due to the PAC5526 and PAC5527 the Power Manager contains a charge pump that is used to generate VCP, which is the high- side gate driver supply voltage. So do not need bootstrap circuit and do not need to charge the bootstrap capacitance during drive, Therefore, support high-side 100% duty cycle output.
