Low-Voltage, Quad-/Hex-/Octal-Voltage
µP Supervisors
The MAX16000–MAX16007 are low-voltage, quad-/hex-/
octal-voltage µP supervisors in small thin QFN and TSSOP
packages. These devices provide supervisory functions
for complex multivoltage systems. The MAX16000/
MAX16001/MAX16002 monitor four voltages, the
MAX16003/MAX16004/MAX16005 monitor six voltages,
and the MAX16006/MAX16007 monitor eight voltages.
The MAX16000/MAX16001/MAX16003/MAX16004/
MAX16006 offer independent outputs for each moni-
tored voltage. The MAX16001/MAX16002/MAX16004–
MAX16007 offer a reset output that asserts whenever
any of the monitored voltages fall below their respective
thresholds or the manual reset input is asserted. The
reset output remains asserted for the reset timeout after
all voltages are above their respective thresholds and
the manual reset input is deasserted. The minimum
reset timeout is internally set to 140ms or can be
adjusted with an external capacitor.
All open-drain outputs have internal 30µA pullups that
eliminate the need for external pullup resistors.
However, each output can be driven with an external
voltage up to 5.5V. Other features offered include a
manual reset input, a tolerance pin for selecting 5% or
10% input thresholds, and a margin enable function for
deasserting the outputs during margin testing.
The MAX16001/MAX16002/MAX16004–MAX16007 offer
a watchdog timer that asserts RESET or an indepen-
dent watchdog output (MAX16005) when the watchdog
timeout period (1.6s typ) is exceeded. The watchdog
timer can be disabled by leaving input open.
The open-drain outputs of the MAX16000–MAX16007
can be configured to detect an undervoltage condition.
Figure 6 shows a configuration where an LED turns on
when the comparator output is low, indicating an
undervoltage condition. These devices can also be
used in applications such as system supervisory moni-
toring, multivoltage level detection, and V
monitoring (Figure 7).
The MAX16000–MAX16007 feature a pin-selectable
threshold tolerance. Connect TOL to GND to select 5%
threshold tolerance. Connect TOL to V
threshold tolerance.

A window detector circuit uses two auxiliary inputs in
the configuration shown in Figure 8. External resistors
set the two threshold voltages of the window detector
circuit. External logic gates create the OUT signal. The
window detection width is the difference between the
threshold voltages (Figure 9).
