General Description
The MAX16060/MAX16061/MAX16062 are 1% accurate,
quad-/hex-/octal-voltage µP supervisors in a small thin
QFN package. These devices provide supervisory func-
tions for complex multivoltage systems. The MAX16060
monitors four voltages, the MAX16061 monitors six volt-
ages, and the MAX16062 monitors eight voltages.
These devices offer independent outputs for each mon-
itored voltage along with a reset output that asserts
whenever any of the monitored voltages fall below their
respective thresholds (down to 0.4V) or the manual
reset input is asserted. The reset output remains assert-
ed 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.
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.
These devices are offered in 16-, 20-, and 24-pin thin
QFN packages (4mm x 4mm) and are fully specified
from -40°C to +125°C.
