MAX16000–MAX16007
Low-Voltage, Quad-/Hex-/Octal-Voltage
μP Supervisors
Detailed Description
The MAX16000–MAX16007 are low-voltage, quad-/hex-/
octal-voltage μP supervisors in small TQFN 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-
Window Detection
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).

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.

Figure 6. Quad Undervoltage Detector with LED Indicators
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.

Undervoltage-Detection Circuit
The open-drain outputs of the MAX16000–MAX16007
OUT2
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 CC bar-graph
monitoring (Figure 7).
