1% Accurate, Quad-/Hex-/Octal-Voltage
µP Supervisors
The MAX16060/MAX16061/MAX16062 are 1% accurate
low-voltage, quad-/hex-/octal-voltage µP supervisors in
a small thin QFN package. These devices provide
supervisory functions for complex multivoltage systems.
The MAX16060 monitors four voltages; the MAX16061
monitors six voltages; and the MAX16062 monitors eight
voltages.
These supervisors offer independent outputs for each
monitored voltage along with 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 respec-
tive thresholds and the manual reset input is deassert-
ed. 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.
An additional feature is a watchdog timer that asserts
RESET when the watchdog timeout period (1.6s typ) is
exceeded. The watchdog timer can be disabled by
leaving WDI unconnected.
The
MAX16061/MAX16062 can be configured to detect an
undervoltage condition. Figure 4 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 sys-
tem supervisory monitoring, multivoltage level detection,
and V
The MAX16060/MAX16061/MAX16062 feature a pin-
selectable threshold tolerance. Connect TOL to GND to
select 5% threshold tolerance. Connect TOL to V
select 10% threshold tolerance.

A window detector circuit uses two inputs in the config-
uration shown in Figure 6. 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 7).
