Power Source Selector for
Dual-Battery Systems
Note 2:
TCOMP undervoltage lockout sets the MAX1773/MAX1773A
’
s internal status bits for the batteries to be designated as
“
absent
”
(V
THM_
> V
TCOMP
).
V
ACDET
must remain above 2.2V, except in power-up.
COMA cannot sink current until V
COMB
> V
BATB
- 2V. Likewise, COMB cannot sink current until V
COMA
> V
BATA
- 2V.
DISA cannot sink current until V
DISB
> V
EXTLD
- 2V. Likewise, DISB cannot sink current until V
DISA
> V
EXTLD
- 2V.
Battery Switchover Delay starts when either V
COM_
or V
DIS_
of the connected battery begins to rise and ends when both
V
COM_
and V
DIS_
of the other battery have fallen 3V below their sources (Figures 1 and 2).
Battery Action Delay starts when the connected battery
’
s voltage falls below 5
V
MINV
and ends when both V
COM_
and
V
DIS_
of the other battery have fallen 3V below their sources (Figures 1 and 2).
Thermistor Action Delay begins when V
THM_
of the connected battery rises above V
TCOMP
and ends when both V
COM
_
and V
DIS_
of the other battery have fallen 3V below their sources (Figures 3 and 4).
AC to Battery Switchover Delay begins when V
ACDET
falls below its threshold and ends when both V
COM_
and V
DIS_
of the
battery being switched to have fallen 3V below their sources (Figure 5).
Note 10:
Battery to AC Switchover Delay begins when V
ACDET
rises above its threshold and ends when V
DIS_
of the battery being
switched from has begun to rise (Figure 6).
Note 11:
CHG_ Turn-on Delay begins when V
CHG_
of the battery being switched from begins to rise and ends when V
CHG_
of the
battery being switched to begins to fall (Figures 7 and 8).
