Product details

3.9V threshold supervisor for single-rail monitoring

The MAX6423XS39+T is a single-voltage supervisor from Analog Devices, monitoring a 3.9V threshold rail with an active-low, open-drain reset output. The reset timeout is adjustable or selectable via external components, giving the designer control over the power-up sequencing delay.

Temperature range and deployment context

The SC-70-4 (SC-82A/SOT-343) package is a compact 4-pin surface-mount footprint, common for supervisor ICs in space-constrained designs like sensor modules or portable instrumentation.

Frequently asked questions

What is the reset output type of the MAX6423XS39+T?

The reset output is active-low, open-drain or open-collector, requiring a pull-up resistor to the monitored rail or the system supply.

What package does the MAX6423XS39+T come in?

It is supplied in an SC-82A/SOT-343 package, also designated as SC-70-4, in strip-pack format for surface-mount assembly.
