All devices are offered with either push-pull or open-
drain outputs (see the Selector Guide ). The MAX6788
has one push-pull output and one open-drain output,
configured as shown in Table 1.
All open-drain outputs require an external pullup resis-
tor. The open-drain pullup resistor may be connected
to an external voltage up to +6V, regardless of the volt-
age at BATT.

Input hysteresis defines two thresholds, separated by
the hysteresis voltage, configured so the output asserts
when the input falls below the falling threshold, and
deasserts only when the input rises above the rising
threshold. Figures 4 and 5 show this graphically.
Hysteresis removes, or greatly reduces, the possibility
of the output changing state in response to noise or
battery-terminal voltage recovery after load removal.
