Hello,
 
Please see the attached file as VLOWV specifications from bq24650 datasheet.



It's my understanding that...
Precharge to Fastcharge transition voltage is 1.55V(typ)
Fastcharge to Precharge transition voltage is 1.45V(typ)
Is my understanding correct ?

If yes, could you please let me know the meaning of  falling deglitch test condition "VFB rising above Vlowv+Vlow_hys".
I couldn't understand meaning of "Vlowv+Vlow_hys".
I think  transition voltage of precharge to fastcharge might be 1.65V.

Best Regards,
Ryuji Asaka
