NOTE 1: The following are tested at V
functionality, logic input leakage, PFI functionality, and the RESET and RESET states. The state of
RESET or RESET and PFO is tested at V
NOTE 2: Tested V
NOTE 3: Leakage current into the battery is tested under the following worst-case conditions: V
= 5.5V, V
NOTE 4: "-" equals the battery-charging current, "+" equals the battery-discharging current.

NOTE 8: The reset threshold tolerance is wider for V
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).
