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

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

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.
