TPS65910能否在对芯片VCC供电的同时通过把PWRHOLD引脚拉高的来使TPS65910开机?

Other Parts Discussed in Thread: TPS65910

在设计中把TPS65910的VCC1, VCC2, VCCIO, VCC3, VCC4, VCC5, VCC6, VCC7都接在5V上,同时PWRHOLD通过电阻分压的方式也接在5V。如果外部5V供电,此时TPS65910的VCC上电,同时PWRHOLD拉高(PWRON接在VRTC上),采用这种tps65910方式是否能够正常开机?PWRHOLD拉高与TPS65910的VCC供电是否需要延时?需要多久的延时?
