General Description
The MAX6400–MAX6405 is a family of ultra-low power
microprocessor (μP) supervisory circuits used for moni-
toring battery, power-supply, and regulated system
voltages. Each device contains a precision bandgap
reference comparator and is trimmed to specified trip
threshold voltages. These devices provide excellent cir-
cuit reliability and low cost by eliminating external com-
ponents and adjustments when monitoring system
voltages from 2.5V to 5.0V. A manual reset input is also
included.
The MAX6400–MAX6405 assert a reset signal whenev-
er the V
CC
supply voltage falls below a preset thresh-
old. These devices are differentiated by their output
logic configurations and preset threshold voltages. The
MAX6400/MAX6403 (push-pull) and the MAX6402/
MAX6405 (open-drain) have an active-low reset (
RESET
is logic low when V
CC
is below V
TH
). The MAX6401/
MAX6404 have an active-high push-pull output (RESET
is logic high when V
CC
is below V
TH
). All parts are
guaranteed to be in the correct output logic state for
V
CC
down to 1V. The reset circuit is designed to ignore
fast transients on V
CC
. The MAX6400/MAX6401/
MAX6402 have voltage thresholds between 2.20V and
3.08V in approximately 100mV increments. The
MAX6403/MAX6404/MAX6405 have voltage thresholds
between 3.30V and 4.63V in approximately 100mV
increments.
Ultra-low supply current of 500nA (MAX6400/MAX6401/
MAX6402) makes these parts ideal for use in portable
equipment. These devices are available in 4-bump
chip-scale packages (UCSP)

reset
thresholds from 2.20V to 4.63V, in approximately 0.1V incre-
ments. Choose the desired reset-threshold suffix from Table 1
and insert it in the blank space following “S”. There are 21 stan-
dard versions with a required order increment of 2500 pieces.
Sample stock is generally held on the standard versions only
(Table 1). Required order increment is 10,000 pieces for non-
standard versions (Table 2). Contact factory for availability. All
devices available in tape-and-reel only.
