PF0100 PFUZE PMIC DVS Voltage Stepping

Dear all,

 

is there any way to figure out in software, when the PF0100 PFUZE PMIC is finished with a voltage stepping sequence?

 

The datasheet (Rev. 8.0) explains in section 6.4.4.2 how the voltage stepping for the buck regulators works and which DVS speed selections can be configured, but I can't find any information on how to determine in software, when such a voltage stepping sequence is finished after reprogramming the voltage-setting for a buck regulator or when the PMIC switches between "normal", "standby" and "sleep" modes.

 

When switching other devices to different power-management modes or turning them on or off, it would be quite important to know, when their respective voltage supply has reached the programmed value.

 

Kind regards,

Marc
