Hi All,

Our Application is battery-based. Mainly we use a cross-over processor—some issues we facing in power supply.
1) In the processor some power blocks minimum voltage of 3V.
2) But our battery will go below 3V, so the processor will go into some hang state.

Before the processor if 3V above then only need to allow power for the processor. Could you please help only one?

After voltage voltage then only need to allow supply to all sections.

 

Use a buck/boost DC to DC converter to power the processor.

 

Thanks for your response

Please check the attached image

In Battery Condition
If Vout > 3V Need to supply a processor
If Vout < 3V Not enter supply processor

 

Use a buck/boost DC to DC converter to power the processor.

Good, as that keeps processor at required volts when volts drop down.
