SPECIFICATIONS (continued)
V
CC
= 3.17V to 5.50V for the SP690T/SP80_T, V
CC
= 3.02V to 5.50V for the SP690S/SP80_S, V
CC
= 2.72V to 5.50V for the SP690R/SP80_R, V
BATT
= 3.60V, and
T
A
= T
MIN
to T
MAX
unless otherwise noted. Typical values taken at T
AMB
= +25
O
C.
NOTE 1:
The following are tested at V
= 3.6V and V
= 5.5V: V
supply current, watchdog
functionality, logic input leakage, PFI functionality, and the RESET and RESET states. The state of
RESET or RESET and PFO is tested at V
= V
(min).
NOTE 2:
Tested V
= 3.6V, V
= 3.5V and 0V.
NOTE 3:
Leakage current into the battery is tested under the following worst-case conditions: V
CC
= 5.5V, V
= 1.8V and at V
= 1.5V, V
= 1.0V.
NOTE 4:
"-" equals the battery-charging current, "+" equals the battery-discharging current.
NOTE 5:
When V
> V
> V
, V
remains connected to V
until V
drops below V
BATT
. The
V
-to-V
BATT
comparator has a small 25mV typical hysteresis to prevent oscillation.
NOTE 6:
BATT
> V
CC
> V
SW
, V
OUT
remains connected to V
CC
until V
CC
drops below the battery
switch threshold, V
.
NOTE 7:
V
switches from V
to V
when V
rises above the reset threshold, independent of
V
. Switchover back to V
occurs at the exact voltage that causes RESET to go HIGH (on the
SP804_ and SP805_ RESET goes LOW). Switchover occurs 200ms prior to reset.
NOTE 8:
The reset threshold tolerance is wider for V
rising than for V
CC
falling to accommodate the
10mV typical hysteresis, which prevents internal oscillation.
NOTE 9:
SP690_ and SP802_ devices only.
NOTE 10:
SP804_ and SP805_ devices only.
NOTE 11:
The leakage current into or out of the RESET pin is tested with RESET asserted (RESET
output high impedance).
