Detailed Description
The MAX6461/MAX6462/MAX6463 voltage detectors
and the MAX6464/MAX6465/MAX6466 P reset supervi-
sory circuits monitor battery, power-supply, and system
voltages from +1.6V to +5.5V. These devices consume
only 1A of supply current with a 3.6V supply voltage.
Whenever VCC falls below the internal VTH- threshold,
the output is asserted and remains asserted until VCC
rises above VTH+ (VTH+ = VTH-
× 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 (VCC) drops below the internal VTH- threshold and remains low
until the monitored input exceeds the internal VTH+ threshold. OUT is asserted
high when the monitored input (VCC) drops below the internal VTH- threshold and
remains high until the monitored input exceeds the internal VTH+ 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
OUT is asserted low when the monitored input (VCC) drops below the internal
VTH- threshold and remains low for at least 150ms after the monitored input
exceeds the internal VTH+ threshold. OUT is asserted high when the monitored
input (VCC) drops below the internal VTH- threshold and remains high for at least
150ms after the monitored input exceeds the internal VTH+ threshold. The open-
drain output OUT requires an external pullup resistor.
