Note 1: V
Note 2: Tested at VBATT = 3.6V, V
Note 3: Leakage current into the battery is tested under the worst-case conditions at V
Note 4: Guaranteed by design.
Note 5: When V
Note 6: When VBATT > V
Note 7: V
Note 8: The reset threshold tolerance is wider for V
Note 9: The leakage current into or out of the RESET pin is tested with RESET asserted (RESET output high impedance).
