V
VBATT = 3.6V, and V
CC
= 5.5V. The state of –————–or RESET and –——Ois tested at V

= V
CC
min.
Note 2:
Tested at VBATT = 3.6V, V
CC
= 3.5V and 0V. The battery current will rise to 10μA over a narrow transition window around
V
CC
= 1.9V.
Note 3:
Leakage current into the battery is tested under the worst-case conditions at V
CC
= 5.5V, VBATT = 1.8V and at V
CC
= 1.5V,
VBATT= 1.0V.
Note 4:
Guaranteed by design.
Note 5:
When V
SW
> V
CC
> VBATT, V
OUT
remains connected to V
CC
until V
CC
drops below VBATT. The V
CC
-to-VBATT comparator
has a small 25mV typical hysteresis to prevent oscillation. For V
CC
< 1.75V (typ), V
OUT
switches to VBATT regardless of the
voltage on VBATT.
Note 6:
When VBATT > V
CC
> V
SW
, V
OUT
remains connected to V
CC
until V
CC
drops below the battery switch threshold (V
SW
).
Note 7:
V
OUT
CC
when V
CC
rises above the reset threshold, independent of VBATT. Switchover back to
V
CC
switches from VBATT to V
switchover occurs 200ms prior to reset.
Note 8:
The reset threshold tolerance is wider for V
CC
rising than for V
CC
falling to accommodate the 10mV typical hysteresis, which
prevents internal oscillation.
Note 9:
The leakage current into or out of the RESET pin is tested with RESET asserted (RESET output high impedance).
