Detailed Description
The MAX6461/MAX6462/MAX6463 voltage detectors
and the MAX6464/MAX6465/MAX6466 μP reset supervi-
sory circuits monitor battery, power-supply, and system
voltages from +1.6V to +5.5V. These devices consume
only 1μA of supply current with a 3.6V supply voltage.
Whenever V
CC
falls below the internal V
TH
- threshold,
the output is asserted and remains asserted until V
CC
rises above V
TH+
(V
TH+
= V
TH
-
×
1.05). All devices have
±
2.5% threshold accuracy over temperature and offer
protection to short voltage transients. These devices are
ideal for low-cost and space-critical applications
because they do not require external components for
proper operation.

NAME
FUNCTION
OUT
Detector Output for the MAX6461/MAX6462/MAX6463: Push-pull (active-low or
active-high) and open-drain (active-low) options.
OUT
is asserted low when the
monitored input (V
CC
) drops below the internal V
TH-
threshold and remains low
until the monitored input exceeds the internal V
TH+
threshold. OUT is asserted
high when the monitored input (V
CC
) drops below the internal V
TH-
threshold and
remains high until the monitored input exceeds the internal V
TH+
threshold. The
open-drain output
OUT
requires an external pullup resistor. Output for the
MAX6464/MAX6465/MAX6466: Push-pull (active-low or active-high) and open-
drain (active-low) options.

OUT
is asserted low when the monitored input (V
CC
) drops below the internal
V
TH-
threshold and remains low for at least 150ms after the monitored input
exceeds the internal V
TH+
threshold. OUT is asserted high when the monitored
input (V
CC
) drops below the internal V
TH-
threshold and remains high for at least
150ms after the monitored input exceeds the internal V
TH+
threshold. The open-
drain output
OUT
requires an external pullup resistor.
