MAX6775–MAX6781
Detailed Description
These battery monitors have an active-low output that
asserts when the input falls below a set voltage. They
also offer hysteresis for noise immunity, and to remove
the possibility of output chatter due to battery terminal
voltage recovery after load removal. They are available
with one or two monitors per package, with push-pull or
open-drain outputs, and with internally set or externally
adjustable hysteresis (dual-channel devices offer only
internally fixed hysteresis). Figures 1, 2, and 3 show
block diagrams and typical connections. See the
Selector Guide for details.
Low-Battery Output
All devices are offered with either push-pull or open-
drain outputs (see the
Selector Guide). The MAX6781
has one push-pull output and one open-drain output,
configured as in Table 1.
On all devices with open-drain outputs an external
pullup resistor is required. The open-drain pullup resis-
tor can connect to an external voltage up to +6V,
regardless of the voltage at BATT.
