Dual-/Triple-/Quad-Voltage, Capacitor-
Adjustable, Sequencing/Supervisory Circuits
General Description
The MAX16025–MAX16030 are dual-/triple-/quad-volt-
age monitors and sequencers that are offered in a
small TQFN package. These devices offer enormous
design flexibility as they allow fixed and adjustable
thresholds to be selected through logic inputs and pro-
vide sequence timing through small external capaci-
tors. 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 is
available with push-pull or open-drain configuration
with the open-drain version capable of supporting volt-
ages up to 28V, thereby allowing them to interface to

o Fully Specified from -40°C to +125°C
Ordering Information
shutdown and enable inputs of various DC-DC regula-
tors. Each detector can operate independently as four
separate supervisory circuits or can be daisy-chained
to provide controlled power-supply sequencing.
The MAX16025–MAX16030 also include a reset func-
tion that deasserts only after all of the independently
monitored voltages exceed their threshold. The reset
