Hi
I have question for about BQ25504 Data sheet Fig 22 means
Question
No1. About Fig 22 each mean
a) Fig .22 0.2V ~ 1.4V (Chip Enable)
What dose mean Chip Enable? and Chip enable purpose??
b) Fig.22 1.4V ~ 1.8V ( Charger Enable)
What dose mean Charger Enable and purpose??
c) Fig.22 1.8V ~ 2.2V ( Under Voltage)
What dose mean under voltage and what happen??
d) Fig 22 under voltage (2.2V) ~ +hyst (internal)
Q : What purpose "under voltage +hyst" and what happen?
e) Fig 22 undervoltage +hyst ~ over voltage - hyst
Q : Wgat purpose "over voltage -hyst" and purpose?
f) Fig22 over voltage - hyst ~ over voltage
Q: What purpose "over voltage ? " and happen?
g) Fig22 over voltage ~ device absolute
Q: What purpose this during over voltage and device absolute and purpose?
No2 Q : Wtat diffrence "Cold start " and "Boost Charger ON" ??
No3. Q: if we set to Over Voltage =3.3V and Under Voltage=2.2.
Which is start rechaege Voltage after dis charge ??
No4. Q: About BAT_OK and OK_PROG, OK_HYST Pin.
If not use these pin which is correct? Open or Pull UP/ Down??
Could you answer to us??
Thanks and Regard
