The MAX16041/MAX16042/MAX16043 are dual-/triple-/
quad-voltage monitors and sequencers that are offered
in a small thin QFN package. These devices offer enor-
mous design flexibility as they allow fixed and
adjustable thresholds to be selected through logic
inputs and provide sequence timing through small
external capacitors. These versatile devices are ideal
for use in a wide variety of multivoltage applications.
As the voltage at each monitored input exceeds its
respective threshold, its corresponding output goes
high after a propagation delay or a capacitor-set time
delay. When a voltage falls below its threshold, its
respective output goes low after a propagation delay.
Each detector circuit also includes its own enable input,
allowing the power-good outputs to be shut off inde-
pendently. The independent output for each detector
has an open-drain configuration capable of supporting
voltages up to 28V, thereby allowing them to interface
to shutdown and enable inputs of various DC-DC regu-
lators. Each detector can operate independently as four
separate supervisory circuits or can be daisy-chained
to provide controlled power-supply sequencing.
The MAX16041/MAX16042/MAX16043 also include a
push-pull reset function that deasserts only after all of
the independently monitored voltages exceed their
threshold. The reset timeout is internally fixed or can be
adjusted externally. These devices are offered in a
4mm x 4mm TQFN package and are fully specified
from -40°C to +125°C.
