Low-Battery Output
The low-battery outputs are available in active-low
( LBO , LBOL , LBOH ), open-drain configurations. The
low-battery outputs can be pulled to a voltage indepen-
dent of V CC or V DD , up to 5.5V. This allows the device
to monitor and operate from direct battery voltage while
interfacing to higher voltage microprocessors.
The MAX6846/MAX6847 single-output voltage monitors
provide a single low-battery output, LBO . LBO asserts
when LTHIN drops below V LTH and remains asserted
for at least 150ms after HTHIN rises above V HTH (see
Figure 2). The MAX6848/MAX6849 dual-output voltage
monitors provide two low-battery outputs: LBOH and
LBOL . LBOH asserts when HTHIN drops below V HTH-
and remains asserted for at least 150ms after HTHIN

rises above V HTH+ . LBOL asserts when LTHIN drops
below V LTH- and remains asserted for at least 150ms
after LTHIN rises above V LTH+ (see Figure 3). For fast-
rising V DD input, the LBOL timeout period must com-
plete before the LBOH timeout period begins.
Reset Output
The MAX6846–MAX6849 provide an active-low reset
output ( RESET ). RESET is asserted when the voltage at
V CC falls below the reset threshold level. Reset remains
asserted for the reset timeout period after V CC exceeds
the threshold. If V CC goes below the reset threshold
before the reset timeout period is completed, the inter-
nal timer restarts (see Figure 4). The MAX6846/
MAX6848 have open-drain reset outputs, while the
MAX6847/MAX6849 have push-pull reset outputs.
