Note 1: V CC supply current, logic input leakage, watchdog functionality (MAX690_/802_/805_/804_), M R functionality
Note 7: V OUT switches from VBATT to V CC when V CC rises above the reset threshold, independent of VBATT. Switchover back to

– –
– — — — — — — –
VBATT = 3.6V, and V CC = 5.5V. The state of R E S E T or RESET and P F O is tested at V CC = 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 ).
– — — — — –
V CC occurs at the exact voltage that causes R E S E T to go high (on the MAX804_/805_, RESET goes low); however
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).
