Can system shut down to protect the battery

hi , dialog
We use the lithium battery to supply the DA14861 system . In order to prevent the battery overdischarge , can DA14681 shut down itself when VBAT voltage is below a preset threshold ? And system can restart when VBAT voltage recover to threshold level.

Device:

DA1468x

Hi guxiang,

Could you please check the paragraph 7.2 Safety Provided by DA1468x of the DA1468x Battery Charging (AN-B-035) document? In this paragraph is described the safety provided be DA1468x. The device supports a brownout detection that switches the DC-DC off when the battery voltage drops below 2.5 V. Also, be aware that the 2.5V limit is not standard and it depends on the manufacturer.

Thanks, PM_Dialog
