The MAX16008/MAX16009 are adjustable quad window
voltage detectors in a small thin QFN package. These
devices are designed to provide a higher level of sys-
tem reliability by monitoring multiple supply voltages
and providing a fault signal when any of the voltages
exceed their overvoltage thresholds or fall below their
undervoltage thresholds.
These devices offer user-adjustable thresholds that
allow voltages to be monitored down to 0.4V. These
devices allow the upper and lower trip thresholds of
each window detector to be set externally with the use
of three external resistors.
Each monitored threshold has an independent open-
drain output for signaling a fault condition. The outputs
can be wire OR’ed together to provide a single fault
output. The open-drain outputs are internally pulled up
with a 30µA current, but can be externally driven to
other voltage levels for interfacing to other logic levels.
Both devices feature a margin input to disable the out-
puts during margin testing or any other time after
power-up operations. The MAX16009 offers a reset out-
put that deasserts after a reset timeout period after all
voltages are within their threshold specifications. The
reset timeout is internally set to 140ms (min), but can
be externally adjusted to other reset timeouts using an
external capacitor. In addition, the MAX16009 offers a
manual reset input.
All devices are offered in a 4mm x 4mm TQFN package
and are fully specified from -40°C to +125°C.
