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.

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.
