is tested at VCC = VCC min.
Note 2: Tested at VBATT = 3.6V, VCC = 3.5V and 0V. The battery current will rise to 10A over a narrow transition window around
VCC = 1.9V.
Note 3: Leakage current into the battery is tested under the worst-case conditions at VCC = 5.5V, VBATT = 1.8V and at VCC = 1.5V,
VBATT= 1.0V.
Note 4: Guaranteed by design.
Note 5: When VSW > VCC > VBATT, VOUT remains connected to VCC until VCC drops below VBATT. The VCC-to-VBATT comparator
has a small 25mV typical hysteresis to prevent oscillation. For VCC < 1.75V (typ), VOUT switches to VBATT regardless of the
voltage on VBATT.
Note 6: When VBATT > VCC > VSW, VOUT remains connected to VCC until VCC drops below the battery switch threshold (VSW).
Note 7: VOUT switches from VBATT to VCC when VCC rises above the reset threshold, independent of VBATT. Switchover back to
VCC occurs at the exact voltage that causes

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 VCC rising than for VCC 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).

ELECTRICAL CHARACTERISTICS (continued)
(VCC = 3.17V to 5.5V for the MAX690T/MAX704T/MAX80_T, VCC = 3.02V to 5.5V for the MAX690S/MAX704S/MAX80_S, VCC = 2.72V to
5.5V for the MAX690R/MAX704R/MAX80_R; VBATT = 3.6V; TA = TMIN to TMAX; unless otherwise noted. Typical values are at TA = +25C.)
