ADP5091 function

Hi

 

I have a question regarding the storage function of the ADP5901

 

Overcharge prevention voltage 3.7 V
Overdischarge prevention voltage 3.0 V

 

Connect to the SETSD and TERM terminals if you want to How much should I set the resistance value.

 

 

Best Regards

    Hi HOD,

    REG_OUT is regulated output that can be selected by VID but SYS is a floating output that can be charged up to TERM threshold. if you want to use this output, it's better to connect ADP5300 or ADP5301 at SYS pin controlled by ADP5091 PGOOD.

    you can tie BACK_UP to ground if you don't use primary battery and tie SETBK to REF. the charing and discharging of BAT is still controlled by SETSD and TERM threshold.

    BR,
